Dr. Rajendra Prasad Central Agricultural University, Pusa

In the imperial Gazetteer of India 1878, Pusa was recorded as a government estate of about 1350 acres in Darbhanba. It was acquired by East India Company for running a stud farm to supply better breed of horses mainly for the army. Frequent incidence of glanders disease (swelling of glands), mostly affecting the valuable imported bloodstock made the civil veterinary department to shift the entire stock out of Pusa. A British tobacco concern Beg Sutherland & co. got the estate on lease but it also left in 1897 abandoning the government estate of Pusa. Lord Mayo, The Viceroy and Governor General, had been repeatedly trying to get through his proposal for setting up a directorate general of Agriculture that would take care of the soil and its productivity, formulate newer techniques of cultivation, improve the quality of seeds and livestock and also arrange for imparting agricultural education. The government of India had invited a British expert. Dr. J. A. Voelcker who had submitted as report on the development of Indian agriculture. As a follow-up action, three experts in different fields were appointed for the first time during 1885 to 1895 namely, agricultural chemist (Dr. J. W. Leafer), cryptogamic botanist (Dr. R. A. Butler) and entomologist (Dr. H. Maxwell Lefroy) with headquarters at Dehradun (U.P.) in the forest Research Institute complex. Surprisingly, until now Pusa, which was destined to become the centre of agricultural revolution in the country, was lying as before an abandoned government estate. In 1898. Lord Curzon took over as the viceroy. A widely traveled person and an administrator, he salvaged out the earlier proposal and got London’s approval for the appointment of the inspector General of Agriculture to which the first incumbent Mr. J. Mollison (Dy. Director of Agriculture, Bombay) joined in 1901 with headquarters at Nagpur The then government of Bengal had mooted in 1902 a proposal to the centre for setting up a model cattle farm for improving the dilapidated condition of the livestock at Pusa estate where plenty of land, water and feed would be available, and with Mr. Mollison’s support this was accepted in principle. Around Pusa, there were many British planters and also an indigo research centre Dalsing Sarai (near Pusa). Mr. Mollison’s visits to this mini British kingdom and his strong recommendations. In favour of Pusa as the most ideal place for the Bengal government project obviously caught the attention for the viceroy.

    Effect of nano urea on soil nitrogen status, uptake, yield and juice quality of Sugarcane in calcareous soil of Bihar
    (RPCAU, Pusa, 2023) Mallick, Jidan Ali; Thakur, S.K.
    The use of nano-fertilizers in agriculture is expanding quickly as a strategy to increase crop yields, nutrient use efficiency and decrease the use of synthetic fertilizers. A novel agricultural input developed through nano technology is called nano urea which provides nitrogen to plants.Nano urea which contains 4% N by weight in nano form. Its use efficiency is higher than that of regular urea and most crops can be benefited from nano urea as a source of nitrogen. A field experiment was therefore, conducted in 2022–2023 at the Crop Research farm Kalyanpur, Dr. Rajendra Prasad Central Agricultural University, Bihar, with an objective to study the “Effect of nano urea on soil nitrogen status, uptake, yield and juice quality of Sugarcane in calcareous soil of Bihar”.The experiment was carried out in RBD design with 10 treatmentswith three replications comprising control, application of nitrogen @ 50, 75 &100 %recommended dose alone or in combination with spray of nano urea (NU) @ 1.0 &2.0% at tillering & grand growth stages. Spray of nano urea @ 2.5% was carried out only at tillering stage. The results revealed that the number of tillers increased significantly from 44.59 - 97.30×103 ha-1 and 62.36 - 110.53× 103 ha-1 at 90 and 120 days after planting with increasing levels of nitrogen. Significant increase in the number of millable cane (67.84 - 76.72 ×103 ha-1) over control was observed due to addition of different doses of nanourea. Applying nano urea had a positive effect on cane yield (61.24 to 79.24 t ha-1) and sugar yield (7.36 to 9.92 t ha-1) but highest cane and sugar yield (81.95 t ha-1 and 10.23 t ha-1 respectively) was observed due to application of recommended dose of nitrogen (RDN). The application of different doses of nano urea did not show significant variation in plant height, cane length, cane girth but single cane weight varied significantly (0.719-1.024 kg) across the different treatments. The application of nano urea in various combinations did not result in statistically significant improvements in cane juice quality parameters like brix, pol, purity, and commercial cane sugar. The highest available nitrogen content (246.14 kg ha-1) was observed in treatment received 100% recommended dose of nitrogen. The available nitrogen content in post-harvest soil varied 224.40 to 236.53 kg ha-1 due to application of nano urea @ 1.0, 2.0 & 2.5% along with 50% and 75% nitrogen fertilizer. Nano urea had no notable impact on the available phosphorus and potassium content of the post-harvest soil. The meanuptake of nitrogen (88.07 to 279.53 kg ha-1), phosphorus (12.4 to 15.36 kg ha-1) and potassium (113.07 to 154.75 kg ha-1) by sugarcane crop varied significantly across the treatments. The benefit-cost ratio in the treatments receiving 75% RDN along with spray of NU @ 1.0, 2.0 and 2.5% were found at par with the maximum BC ratio (1.89) observed in treatment receiving 100% RDN. Thus,application of 1% nano urea at tillering and grand growth stage along with 75% RDN may be used for sugarcane production in calcareous soil of Bihar.

    Impact of residue incorporation and zinc fertilization on soil health and micronutrient contents of rice grain
    (RPCAU, Pusa, 2023) PRIYADARSHANI, CHITRA; Laik, Ranjan
    The major goals of researchers under intensive cropping systems, especially in Asian countries, where demand for food is very high due to population pressure, is to achieve higher productivity, better quality produce and sustenance of soil health. Hence, a study on long term crop residue incorporation (29 years) and zinc fertilization effects was done to understand how these practices synergistically enhance soil health, rice productivity and nutritional quality of rice grain under rice-wheat cropping system. This research was conducted in a potentially Zn deficient calcareous soil at RPCAU research farm in a Split Plot Design (SPD) with different crop residue levels at 0%, 25%, 50%, and 100% in the main plot and varying Zn levels at 0, 2.5, 5.0, and 10.0 kg ha-1 in the sub-plot. Zinc was administered at the different levels initially at the commencement of the study and subsequently reapplied after a span of 25 years (during 2018). On the other hand, crop residue was incorporated into the soil every year following the harvest of each crop. Combining complete crop residue incorporation with residual 10 kg Zn ha-1 boosts soil organic carbon, available nitrogen, and overall soil health, benefiting aggregation, water retention, and nutrient availability. Long-term incorporation leads to higher rice yields, improved grain protein, zinc and iron content, correlating positively with enhanced soil health determined by PCA analysis, except for available B, Cu, and Mn.

    Effect of NPK, FYM and Zn application on transformation of Zn, biological properties and nutrient availability under rice-wheat cropping system in calcareous soil
    (RPCAU, Pusa, 2023) KACHHAP, AANCHAL; Kumar, Vipin
    The present study aimed to investigate the effect of NPK, FYM, and Zn application within a RWCS in calcareous soil on various aspects, including yield, nutrient uptake, chemical properties, and biological characteristics of post-harvest soil of second wheat crop in the year 2023. Additionally, the study examined different fractions of zinc in the soil and their correlations with each other, as well as with yield, nutrient uptake, and available zinc content. The research was conducted as a field experiment that commenced during the kharif season of 2021 at the Pusa Research Farm of RPCAU Samastipur, Bihar. The experimental layout followed a randomized block design comprising ten treatments replicated three times. These treatments included a range of conditions: T1 as the absolute control, T2 with RDF (Recommended Dose of Fertilizers), T3 with RDF and FYM @ 5 t ha-1, T4 with RDF and foliar spray of 0.5% ZnSO4, T5 with RDF and 5 kg Zn ha-1, T6 with RDF and Geoxol.com @ 40 kg ha-1, and T7, T8, T9, T10 similar to T2, T3, T4, T5, respectively, but with an increased RDF level of 125%. Among these treatments, T10 (125% RDF + 5 kg Zn ha-1) exhibited the highest yield of 5.21 t ha-1 and 4.64 t ha-1 with grain yield response of about 6.3 to 27.1 and 0.21 to 0.90 per cent in rice and wheat crop respectively. However, when considering nutrient uptake, T8 (125% RDF + FYM @5 t ha-1) showed the greatest total nutrient uptake, and it was statistically similar to treatments involving increased fertility levels in combination with organic supplementation and zinc sources. Remarkably, substantial nutrient availability (N, P, K, S, and Zn) was detected in treatments with enhanced fertility levels, both independently and in various combinations. Moreover, treatment T8 demonstrated noteworthy dominance in biological properties, indicating that FYM and higher fertilizer levels played a pivotal role in stimulating microbial growth. This heightened response was most pronounced in treatments involving 125% RDF, either alone or in combination, mainly due to the initial nutrient deficiency of the soil. Analyzing different zinc fractions in the post-harvest soil indicated that the water-soluble and exchangeable forms were minimal, while the residual form was predominant revealing that the majority of total zinc resided in the residual form. Interestingly, positive and significant correlations were observed among yield, nutrient uptake, and available zinc content. The order of dominance of different zinc fractions in the soil was: Residual-Zn > Organically bound-Zn > Zn bound to crystalline oxide > Zn bound to amorphous oxide > Complexed-Zn > Water soluble plus exchangeable-Zn. These findings inform agricultural practices and soil management strategies to farmers by emphasizing the benefits of balanced NPK fertilization with organic supplementation and zinc for improved crop yields. They underscore the importance of addressing micronutrient deficiencies, particularly zinc, and highlight the role of organic matter in enhancing soil health. Additionally, the study offers insights into nutrient build-up and zinc distribution, guiding more efficient soil fertility strategies. Overall, these findings promote a holistic approach to soil and nutrient management, enhancing sustainability in agriculture.

    Development of Targeted Yield Equations for Aerobic Rice (Var. Rajendra neelam) under Integrated Nutrient Management
    (Dr.RPCAU, Pusa, 2022) KUMAR, NARESH; SUMAN, S. N.
    Field experiment was conducted at Pusa farm, RPCAU during the year 2021 to generate Targeted Yield based Fertilizer prescription equations for aerobic rice Var. Rajendra neelam under integrated nutrient management system. In order to develop fertilizer prescription equations, complex experiment of rice was conducted at nursery jhilly field with aerobic rice (cv. Rajendra neelam) by superimposing 24 treatments consisting of four levels of N (0, 60,120 and180 kg/ha), four levels of P2O5 (0, 30, 60 and 90 kg/ha), four levels K2O (0, 20, 40 and 60 kg/ha) and three level of vermicompost (0, 1 and 2 t/ha). The integrated nutrient management approach had a positive impact on organic carbon, soil available nutrient status, crop yield, and nutrient uptake by aerobic rice. When compared to other treatments, a combined application of 120 kg nitrogen, 60 kg phosphorus, and 40 kg potassium per hectare, along with 2 t/ha vermicompost resulted in the highest available NPK in soils with the highest crop yield and nitrogen, phosphorus and potassium uptake by aerobic rice. Fertilizer prescription equations were formulated for aerobic rice by following Ramamurthy’s Inductive-cum-targeted yield approach. Based on the experiment in the nutrient requirement (NR) for producing one quintal of aerobic rice was found to be 4.09, 0.90, 2.16 kg/q with respect to N,P and K respectively. The NPK contributions to aerobic rice from fertilizers were 48.11, 38.74, and 58.46 % respectively. Conversely, the percentage contribution of NPK from organic component that is organic efficiency was 7.34%, 4.25 %, 5.3%. Based on NR, CS, CF and CO the fertilizer prescription equations were developed for aerobic rice variety (Rajendra neelam) and an estimate of fertilizer dose were formulated in the form of ready reckoner for a range of soil test values and desired yield targets.

    EFFECT OF INTEGRATED NUTRIENT MANAGEMENT ON PRODUCTIVITY AND QUALITY OF SUGARCANE IN CALCAREOUS SOIL
    (Dr.RPCAU, Pusa, 2022) KUMAR, BRAJESH; Sinha, S.K.
    At Dr. Rajendra Prasad Central Agricultural University in Bihar, a field experiment was carried out to investigate the “Effect of integrated nutrient management on productivity and quality of sugarcane in calcareous soil” during 2021–2022.Vermicompost, green manuring (green gram), fertilizer-NPK (150:85:60) and biofertilizer (Azotobacter and PSB) were used as part of the treatments. The vermicompost was applied at planting and green gram was applied 60 days after planting (DAP). During the spring, sugarcane crop (cv. CoP 112 early) was planted. The germination percent was found non-significant and it varied from 36.5-43.4% and 46.5-55.5% at 45 and 60 days after planting respectively. Compared to strict control and 100% RDF, the combined application of organic, inorganic and biofertilizer produced a much higher number of tillers. The dry matter accumulation at 90,120 and 150 days after planting was found significant while at harvest stage it was found nonsignificant. The number of millable canes varied significantly and ranged from 70.5 × 103 to 125.4 × 103 ha-1. The maximum NMC (Number of millable cane) was obtained in the treatment receiving RDF together with vermicompost and biofertilizer (Azotobacter and PSB). Due to different treatments, the mean cane yield varied significantly and ranged from 41.8 to 94.0 t ha-1. The treatment group receiving RDF coupled with vermicompost and biofertilizer had the highest cane yield, whereas the group receiving absolute control (no fertilizer) had the lowest. Sugar yield is a function of cane yield and followed a similar trend to cane yield. The mean sugar yield varied significantly from 4.5 - 10.5 t ha-1. Brix, pol, purity coefficient and commercial cane sugar was found non-significant. The soil available N (224.33 - 278.92 kg ha-1), available P (22.28 - 36.33 kg ha-1), available K (124.67 - 165.20 kg ha-1) and available S (12.64 - 19.21 mg kg-1) varied significantly due to application of integrated nutrient management in soil. The use of organic and inorganic fertiliser sources over absolute control was also noted as a considerable increase in the Fe, Zn, Cu and Mn content of post-harvest soil. The soil organic carbon stock was found to be non-significant due to the application of nutrients from organic and inorganic fertiliser while the mean soil organic carbon (0.48 - 0.56%), soil microbial biomass carbon (129.10 - 255.90 mg kg-1), and CO2 evolution (36.83 - 60.70 mg 100g-1 soil 24 hr-1) varied significantly. The microflora population in post-harvest soil was significantly higher in treatment receiving RDF along with vermicompost and biofertilizer (Azotobacter and PSB). Due to the impact of various nutrient combinations, the absorption of N (126.97 - 292.58kg ha-1), P (12.54 - 29.96 kg ha-1), and K (114.43 - 271.43kg ha-1) varied significantly. The trend of cane output was similar to the intake of minerals. The effect of various treatment on agronomic use efficiency and physiological use efficiency was varied significantly.

    Impact of intensive fertilizer use on soil health under maize based cropping system
    (Dr.RPCAU, Pusa, 2022) KANDARI, ABHISHEK SINGH; Tiwari, Sanjay
    A study was conducted in the block Khodawandpur (Begusarai) among farmers taking different cropping system (rice-maize, pigeon pea-maize, soybean-maize, maize-wheat and rice-wheat) to study the influence of fertilizer application on soil health. Several soil quality parameters were assessed during the experiment to assess the influence of five cropping systems on soil quality and then it was correlated with the yield of crops in different cropping system. The soil pH variations ranged from 8.01 to 8.26 at the surface layer (0-15cm) and from 8.18 to 8.32 at the sub surface layer (15-30cm). The rice-wheat cropping system had the lowest soil pH (8.01), followed by the rice-maize and pigeon pea-maize cropping system, which might be ascribed to soil submergence during rice cultivation and a higher amount of leaf litter falling over the field throughout crop life of the latter cycle. The range of electrical conductivity variations was determined to be 0.30 to 0.40 dS m-1. The low salt content observed in the pigeon pea cropping system at both soil layers exhibited greater variability than other cropping system. The pigeon pea cropping system has the highest organic carbon content (0.46%), followed by soybean-maize (0.41%) cropping system. The addition of organic carbon and the application of varied doses of inorganic fertilizers caused significant differences in soil available nitrogen in this study under different cropping systems. Nitrogen availability ranged from 137.98 to 178.12 kg ha-1. The maximum quantity of available nitrogen was reported in the pigeon pea cropping system might be attributed to plant biomass deposition and biological nitrogen fixing. Available phosphorus status in soil varied from 31.71 to 44.50 kg ha-1 and it followed the order: pigeon pea-maize>soybean-maize> maize-wheat> rice-wheat> rice-maize. At the surface soil layer, pigeon pea-maize cropping system had the highest soil available potassium (188.84 kg ha-1) and rice-maize cropping system had the lowest (148.24 kg ha-1). Micronutrients varied less in the cropping system. DTPA extractable Fe levels were found to be high in all the cropping systems. DTPA extractable Cu and DTPA extractable Mn were found to be higher in rice-wheat cropping systems, with mean values of 1.93 mg kg-1 and 4.87 mg kg-1, respectively. The large range in Zn concentration in surface soil (0-15cm) was observed under various farming systems. The highest levels of DTPA extractable Zn were found in pigeon pea-maize cropping systems (0.83 mg kg-1). Farmer’s fertilizer and other management techniques may be the reason behind Zn deficiency in soil. The bulk density of the pigeon pea-maize cropping system was found to be lowest (1.37 Mg m-3), whereas rice-wheat had the highest bulk density with a mean value of 1.41 Mg m-3.There was less variation in bulk density among all the cropping system. Relatively high density values were detected in the subsurface layer. Data from several cropping systems revealed that almost all the cropping systems had lower mean values of maximum water holding capacity attributed to intensive tillage and other cultural practices used by farmers. The top layer of a pigeon pea-maize cropping system had the maximum water holding capacity (32.04%), whereas the sub-surface layer of the same cropping system had 28.55%.. Water stable aggregates ranged between 23.23% to 31.03%. The pigeon pea-maize cropping system resulted in the highest mean values (31.03%), whereas the rice-maize cropping system was found to have lowest values (23.23%). Subsurface layer values were found to be lower than surface layer. Soil respiration was highest in the pigeon pea-maize cropping system (1.10 mg CO2 g-1) and lowest in the rice-maize cropping system (0.69 mg CO2 g-1). Organic material was not included during cultural activities in the majority of the farmer’s field resulting in lower soil biological parameters. Cropping systems had active C levels ranging from 169.20 mg kg-1 to 207.93 mg kg-1. In 0-15cm soil depth, the pigeon pea cropping system had the highest mean value, whereas the rice maize cropping system had the least. The dehydrogenase and fluorescein diacetate in the top surface layer ranged from 70.92 to 84.30 (μg TPF g-1 24 h-1) and 2.64 to 4.17 (μg Fluorescein g-1 soil hr-1). Legume based cropping system had the highest dehydrogenase and fluorescein diacetate in the soils of the cropping systems, while rice-maize had the least. The low quantities of dehydrogenase and fluorescein diacetate enzymes found in rice-maize might be linked to low organic carbon content and poor agricultural techniques. Yield of the crops under different cropping system was found to be significantly and positively correlated with most of the soil health parameters but in case of bulk density it was found to be negatively correlated.

    Study of Changes in Soil Properties and Ground Water Quality at Industrial Effluent Disposal Site of Bela at Muzaffarpur District
    (Dr.RPCAU, Pusa, 2021) RANI, SONAL; SINGH, A. K.
    The present investigation had been planned to see a potential change in soil and ground water contamination due to disposal of industrial effluents in surrounding areas of Bela at Muzaffarpur district. Altogether, 15 soil and ground water each sample from various sources were collected at different locations in vicinity of the discharge point of the tannery effluents at 100m interval. The data obtained from the investigation revealed that there was 230% increase in organic carbon, 183% increase in Nitrogen content, 121% increase in Phosphorus, 72% increase in Iron and 318% increase in Chromium in surface soils at discharge point of the effluent water as compared to the farthest point (1400m) from the disposal site. Tannery industrial effluents contains 124% more salt content, 330% more Na, 122% more Chloride, 103% more Ca+ Mg, 113% more carbonate + bicarbonates, 245% more SAR, 18% more Iron and 175% more Cr than groundwater, which makes it unsuitable for irrigation. However, the results indicated that by and large, effluent water contained more amount of much amount of all quality parameters followed by hand pump followed by deep Tube well. Based on the irrigation classes, majority of the ground water samples fall under C2S2 class which indicated that the ground water can safely be used for irrigation purpose. Further, observations confirmed that majority of the ground water samples of various sources (away from the disposal sites) may be used as effective sources of irrigation. However, a few samples nearby vicinity of disposal sites were fall under C3S4 class, which were not found safe for irrigation.

    RELATIONSHIP OF PHYSICO-CHEMICAL PROPERTIES WITH SULPHUR FRACTIONS IN CALCAREOUS SOILS OF BIHAR
    (Dr.RPCAU, Pusa, 2021) JAISWAL, SHUBHAM; Tiwari, Sanjay
    The present investigation on the relationship of different physico-chemical properties with different pools of sulphur was carried out on the bulk of soil samples collected from four different districts (Samastipur, Muzaffarpur, East Champaran and West Champaran). These 160 soil samples from four districts were chosen on the basis of variations in their available sulphur content. Thus, 20 sulphur deficient and 20 sulphur sufficient soil samples were considered for the study. Among the different forms of sulphur, organic sulphur constituted the major fraction of total sulphur, while water soluble-S and sulphate -S being the minor fractions of total-S. The pH, CaCO3, organic carbon and sand fraction emerged as the most dominant soil properties in determining the variations in different forms of S as evidenced by correlation studies. The trend of variations in different pools of sulphur was found as; total S > organic S > residual S > inorganic S > sulphate S > water soluble S among the different districts considered for the study. The significant and positive correlations among different forms of S evinced the existence of dynamic equilibrium among their various forms. Correlation coefficient (r) study between different physico-chemical properties and different pools of sulphur showed that sand, clay, pH, free CaCO3 and organic carbon contents emerged as most promising soil physical and chemical parameters in governing the availability of different forms of sulphur in soils of these four districts.

    IMPACT OF LONG-TERM SOIL TEST CROP RESPONSE BASED FERTILIZER APPLICATION ON PHOSPHORUS AVAILABILITY IN CALCAREOUS SOIL UNDER RICE- WHEAT CROPPING SYSTEM
    (DR.RPCAU, Pusa, 2021) KUMAR, SHASHIKANT; Jha, Shankar
    A field experiment was conducted to study the effect of long-term soil test crop response based fertilizer application on phosphorus availability in calcareous soil under rice-wheat cropping system during Kharif 2019 at Dr. Rajendra Prasad Central Agricultural University, Pusa, Samastipur. The treatments comprised of STCR based yield target approach with 35, 40 and 45 q ha-1 with or without IPNS and in IPNS, 5 tonnes of compost ha-1 were applied. Among the different fraction Ca-P was the dominant fraction followed by Residual P. The different phosphorus forms comprised of Labile P (3.17 – 9.93 kg ha-1), Fe/Al P (9.95 – 23.88 kg ha-1), Ca-P (258.27 – 374.19 kg ha-1), Occluded P (16.62 – 33.41 kg ha-1), Residual P (76.34 – 120.28 kg ha-1), Organic P (37.77 – 127.41 kg ha-1) and Total P (405.41 – 661.43 kg ha-1) in surface soil and Labile P (1.10 – 4.42 kg ha-1), Fe/Al-P (5.46 – 8.37 kg ha-1), Ca-P (135.31 – 240.71 kg ha-1), Occluded P (9.49 – 19.86 kg ha-1), Residual P (68.24 – 94.98 kg ha-1), Organic P (16.98 – 45.09 kg ha-1) and Total P (237.97 – 384.29 kg ha-1) in sub surface varied significantly due to different treatment combination. The treatment T9 with YT of 45 q ha-1 + IPNS shows maximum of labile P, Fe/Al-P, Occluded P, Residual P and Organic P in both the depth of soil and Total P was found highest in T9 under surface layer of soil but in sub surface, it was observed highest under T3 receiving general recommended dose. Ca-P was found highest in treatment T3 receiving general recommended dose in both the layer of soils. The soil available P (3.28 – 6.52 kg ha-1 in surface layer and 1.39 – 3.46 kg ha-1 in sub surface layer) before sowing of rice and available P in post harvest soil (2.79 – 5.89 kg ha-1 in surface layer and 1.17 – 2.46 kg ha-1 in sub surface layer) varied significantly as per the treatments. The treatment T9 with YT of 45 q ha-1 + IPNS shows maximum amount of available P in both pre sowing as well as post harvest soil. The mean bulk density value ranged between 1.30 – 1.40 Mg m-3 and water holding capacity ranged between 31.51 – 35.18 %. Lowest bulk density and highest water holding capacity found in the treatment T9 with YT of 45 q ha-1 + IPNS. Alkaline phosphatase activity found much higher over Acid phosphatase might be due to calcareous nature of soil. The treatment T9 with YT of 45 q ha-1 + IPNS shows significant higher activity of alkaline phosphatase (41.09 μg PNP g-1h-1 in surface and 24.20 μg PNP g-1h-1 in sub surface soil), acid phosphatase (0.527 μg PNP g-1h-1 in surface and 0.081 μg PNP g-1h-1 in sub-surface layer of soil) and PSB (19.27 104 cfu g-1) over control. Overall, the highest plant P uptake was also observed in the treatment T9 (13.59 kg ha-1) with YT of 45 q ha-1 + IPNS followed by T6 (12.89 kg ha-1) with YT of 45 q ha-1. Grain yield and straw yield is a direct function of different growth and yield attributes of plants like plant height, number of tillers/m2, number of grain/panicle, test weight etc. The treatments T9 with YT of 45 q ha-1 + IPNS shows maximum plant height (125.9 cm), number of tillers/m2 (199), number of grains/panicle (135) followed by T6 with YT of 45 q ha-1. Test weight didn’t show any significant changes amongst the different treatments. This increase in all the growth and yield attributes of plants under T9 resulting in increase in grain and straw yield. Grain and straw yield of T9 (4.43 and 5.52 t ha-1) was observed significantly higher over the control. P balance was found negative under the control and it shows increasing trend with increase in fertilizer dose. Lower P balance was observed in integrated plot might be due to low input, more uptake and better utilization of nutrients. Available P was found positively and significantly correlated with alkaline phosphatase, PSB, acid phosphatase, different forms of P except Ca-P and water holding capacity in surface soil. It was found to be negatively correlated with bulk density of soil. Under sub-surface condition, available P was found to be positively and significantly correlated with alkaline phosphatase, acid phosphatase, all other forms of P except Ca-P and Total P. STCR based IPNS treatment not only helps in achieving the yield target with least use of input but also helps in improving the condition of soil health and increasing the farm income.
