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.

ThesisItem Open Access Studies on weed management practices in Kharif maize (Zea mays L.)(Dr. Rajendra Prasad Central Agricultural University, Pusa (Samastipur), 2016) Kurre, Dharmendra Kumar; Bharati, VikramAn experiment on “Studies on weed management practices in Kharif maize (Zea mays L.)” was conducted at TCA Dholi, farm, Muzaffarpur during Kharif 2015.The treatments comprised of atrazine, pendimethalin, halosulfuron, 2, 4-D, metribuzine, power weeder and hand weeding arranged in RBD design with twelve treatments. The soil of the experimental plot was alkaline in reaction (pH 8.3), medium in organic carbon andlow in available N, P2O5, K2O, S and Zn. QPM maize cultivar ‘Shaktiman-5’ was sown at a distance of 60 cm × 20 cm using the seed rate of 20 kg/ha with recommended package of practices. Weed free (hand weeding twice at 20 DAS and 40 DAS) and atrazine @ 1.5 kg/ha (PE) fb halosulfuron @ 60 g/ha (PoE) provided significant weed control during the critical crop-weed competition period (upto 60 DAS). These treatments also recorded the lowest weed density, dry weight and weed index with higher weed control efficiency at all crop growth stages. Which contributes in highest yield attributes viz., cob/plant, grains/cob and test weight and grain yield (49.30 q/ha) and (48.50 q/ha) of maize along with net return ( 48,505 /ha) and ( 40,708/ha) which was found statistically at par with pendimethalin (1000 ml/ha) as (PE) fb atrazine (750 g/ha) + 2, 4-D dimethyl amine (75 %) at 25 DAS as (PoE). Uncontrolled weed growth reduced the grain yield to an extent to 37.40 %. Highest B:C ratio (1.58) was recorded under by atrazine @ 1.5 kg/ha (PE) fb halosulfuron @ 60 g/ha (PoE) which was found statistically at par with pendimethalin (1000 ml/ha) as (PE) fb atrazine (750 g/ha) + 2, 4-D dimethyl amine (75 %) at 25 DAS as (PoE).ThesisItem Open Access Response of Soybean[Glycine max (L)]genotypes to methods of Sowing and Phosphorus levels.(Dr. Rajendra Prasad Central Agricultural University, Pusa (Samastipur), 2016) Kumar, Lokesh; Sinha, K. K.A field experiment entitled “Response of soybean genotypes to methods of sowing and phosphorus levels” was carried out during kharif season of 2015 at Agricultural Research Farm of Tirhut College of Agriculture, Dholi, (Muzaffarpur), a campus of Dr. Rajendra Prasad Central Agricultural University, Pusa (Samastipur), Bihar, (India). The treatments comprised two planting methods [Flat bed method (S1) and Ridge and furrow method (S2)] in main plots and combination of three phosphorus levels [P @ 25 kg/ha (P1), P @ 50 kg/ha (P2) and P @ 75 kg/ha (P3)] and three genotypes [JS-335 (V1), PS-1092 (V2) and SL-688 (V3)] in sub-plots. The treatments were replicated thrice in split plot design. The soil of the experimental plot was sandy loam in texture, alkaline in reaction (pH -8.12), low in organic carbon & available N, P2O5 ¬and K2O in medium range. The soybean varieties were sown at a distance of 45 × 5 cm using the seed rate of 75 kg/ha with recommended N and K doses. Among the planting methods, ridge and furrow method proved significantly superior in all the growth parameters (plant height, number of leaves per plant, number of root nodules, dry matter accumulation, crop growth rate and leaf area index), yield attributes and yield. The ridge and furrow method of planting also significantly improved the grain yield of soybean by 18.08 % over flat bed method. Phosphorus levels, also significantly influenced the all growth parameters (plant height, number of leaves per plant, number of root nodules, dry matter accumulation, crop growth rate and leaf area index), yield and yield attributing parameters. Application of Phosphorus @ 75 kg/ha significantly enhanced the grain yield (16.96 q/ha) by 46.48 % over phosphorus @25 kg/ha under sandy loam condition. Genotypes also showed significant variation on all the growth parameters (plant height, number of leaves per plant, number of root nodules, dry matter accumulation, crop growth rate and leaf area index), yield and yield attributing parameters. Genotype PS-1092 significantly enhanced the grain yield over other two genotypes. Increment in grain yield of soybean under ridge and furrow method of planting resulted in significantly higher gross return ( 73190/ha) and net return ( 48512/ha) as compared to flat bed method. On the basis of economics of soybean under phosphorus levels, it was found that highest gross return ( 72918/ha), net return ( 47702/ha) and B: C ratio (1.88) was incurred with application of phosphorus @ 75 kg/ha. Genotypes PS-1092 recorded the highest gross return ( 74258/ha), net return ( 50162/ha) and B: C ratio (2.08) which was significantly higher than other two genotypes.ThesisItem Open Access Bio-efficacy of Herbicides Combinations Against Weed Flora in Transplanted Rice (Oryza sativa L.)(Dr. Rajendra Prasad Central Agricultural University, Pusa (Samastipur), 2016) Singh, Gourav Pratap; Roy, D. K.A field experiment was undertaken during kharif season of the year 2015 at the Research Farm of Rajendra Agricultural University, Pusa (Samastipur), Bihar to study the “Bio-efficacy of Herbicides Combinations Against Weed Flora in Transplanted Rice (Oryza sativa L.)”. The experiment was conducted in randomized block design having 12 treatments. T1- bispyribac- Sodium @ 25 g/ha at 25 DAT, T2- penoxsulam 24 % SC @ 22.5 g/ha at 15 DAT, T3- bispyribac – sodium + ethoxysulfuron @ 25 +18.75 g/ha at 25 DAT, T4- bispyribac – sodium + chlorimuron + metsulfuron( Almix) @ 20 + 4 g/ha at 25 DAT T5- pretilachlor @ 750 g/ha at 0-3 DAT fb ethoxysulfuron @ 18.75 g/ha at 25 DAT T6- pretilachlor @ 750 g/ha at 0-3 DAT fb chlorimuron + metsulfuron( Almix) @ 4 g/ha at 25 DAT, T7- pyrazosulfuron @ 20 g/ha at 0-3 DAT fb chlorimuron + metsulfuron( almix) @ 4 g/ha at 25 DAT, T8- penoxsulam + cyhalofop 6 % OD (RM) @ 135 g/ha at 15-20 DAT, T9- triafamone + ethoxysulfuron 30 % WG @ 60 g/ha at 15 DAT, T10- pendimethalin (38.7 % CS) @ 750 g/ha at 0-3 DAT fb bispyribac –sodium @ 25 g/ha at 25 DAT, T11- Hand weeding at 25 and 45 DAT and T12- Weedy check replicated thrice with Rajendra Shweta as the test variety. All the weed management practices either herbicidal or hand weeding had profound effect on growth and yield attributes as well as the ultimate yield as reflected in their superiority over the weedy check. Amongst herbicidal treatments pendimethalin (38.7 % CS) @ 750 g/ha at 0-3 DAT fb bispyribac –sodium @ 25 g/ha at 25 DAT was superior to rest of herbicidal treatments. It was also at par with hand weedings at 25 and 45 DAT. pendimethalin (38.7 % CS) @ 750 g/ha at 0-3 DAT fb bispyribac –sodium @ 25 g/ha at 25 DAT recorded top spot in almost all the growth and yield attributing characters and also in the yields of grain and straw. The results pertaining to weed population, weed dry weight and nutrient uptake by weeds and crop separately were a close reflection of growth and yield pattern whereas hand weeding which was superior to all the herbicidal treatments. Amongst herbicidal treatments pendimethalin (38.7 % CS) @ 750 g/ha at 0-3 DAT fb bispyribac –sodium @ 25 g/ha at 25 DAT was superior to rest of herbicidal treatments. Weed control efficiency of pendimethalin (38.7 % CS) @ 750 g/ha at 0-3 DAT fb bispyribac –sodium @ 25 g/ha at 25 DAT (63.10%) and weed index (4.15%) was superior to bispyribac– sodium + ethoxysulfuron @ 25 +18.75 g/ha at 25 DAT (54.89%) and weed index (7.32%) respectively. Protein content in grain was similar in all the treatments except the weedy check in which it was significantly lower. The most glaring part of the results rested in its economic studies, where in all the herbicidal treatments either pre-emergence applications or combination of pre and post emergence applications fetched higher net return and scored better B:C ratio than the two hand weedings. Pendimethalin (38.7 % CS) @ 750 g/ha at 0-3 DAT fb bispyribac –sodium @ 25 g/ha at 25 DAT ( 42,525/ha) cornered the highest net return closely followed by bispyribac– Sodium + ethoxysulfuron @ 25 +18.75 g/ha at 25 DAT ( 41,390/ha). As against these treatments, the net return realized by two hand weedings was lower 37,450/ha. The B:C ratio further widened the gap between manual weeding and herbicidal applications. The highest B:C ratio of 2.61 was recorded from pre-emergence application of bispyribac– Sodium + ethoxysulfuron @ 25 +18.75 g/ha at 25 DAT which was closely followed by pendimethalin fb bispyribac-sodium (2.59) and two hand weedings had a B:C ratio of only 2.06 which was next only to the weedy check (1.81). Thus, it may be summed up that pendimethalin fb bispyribac-sodium is superior to rest of herbicidal treatments. Secondly, high cost involved in manual weeding makes herbicidal treatments more viable preposition. Pendimethalin (38.7 % CS) @ 750 g/ha at 0-3 DAT fb bispyribac –sodium @ 25 g/ha at 25 DAT and bispyribac– sodium + ethoxysulfuron @ 25 +18.75 g/ha at 25 DAT are two most effective herbicidal treatments in transplanted rice for control of complex weed flora and higher economic return.ThesisItem Open Access Effect of nitrogen scheduling on growth, yield and nitrogen use efficiency in rice under different establishment methods.(Dr. Rajendra Prasad Central Agricultural University, Pusa (Samastipur), 2016) Kumar, Prakhar; Chaudhary, S. K.A field experiment entitled “Effect of nitrogen scheduling on growth, yield and nitrogen use efficiency in rice under different establishment methods” was carried out at the Research Farm of Dr. Rajendra Prasad Central University, Pusa, Samastipur, Bihar (India), during kharif season of 2015. The soil of experimental field was calcareous clay-loam alkaline in reaction with pH 8.6. It was moderately fertile being low in organic carbon (0.36%), available nitrogen (212 kg N ha-1), phosphorous (17 kg P2O5 ha-1) and potassium (103 kg K2O ha-1). The factors under study comprised of (A) Establishment methods (3 levels): M1- Transplanting, M2- DSR-dry and M3- DSR-wet in main plot and (B) Nitrogen Scheduling (6 levels): N1- LCC-3, N2- LCC-4, N3- LCC-5, N4- RDN (120 kg N ha-1) (50% B + 25% AT + 25% PI), N5- Neem coated urea (100 % B) and N6- Control in sub plot. The experiment was conducted in split plot design replicated thrice. ‘Rajendra Suwasani’ was taken as a test crop. 60 kg P2O5, 40 kg K2O and 25 kg ZnSO4 per hectare was used. Nitrogen was applied as per treatment. Whereas, full dose of P2O5 and ZnSO4 was applied as basal at the time sowing/transplanting. K2O was applied in two splits 75% as basal and 25% at panicle initiation stage. Among different rice establishment methods, transplanting method registered the maximum grain yield (39.11 q ha-1) and N-use efficiency (25.54%) which remain comparable to DSR-wet. Under different nitrogen scheduling, LCC-4 recorded maximum grain yield (44.12 q ha-1) and it was significantly superior to rest of the treatments except neem coated urea. However, N-use efficiency was maximum in neem coated urea and it was remaining at par with LCC-4. Among different establishment methods, maximum net return (₹ 22,614 ha-1) and B:C ratio (0.77) were observed in DSR-dry. Under nitrogen scheduling, maximum net return (₹ 31,468 ha-1) and B:C ratio (1.03) was recorded in neem coated urea and it was comparable with LCC-4. Thus LCC based nitrogen scheduling resulted in better synchronization between crop N demand and supply. ***ThesisItem Open Access Effect of micro and secondary Nutrients on Growth, Yield and Quality of Black Gram (Vigna mungo (L) Hepper)(Dr. Rajendra Prasad Central Agricultural University, Pusa (Samastipur), 2016) Yadav, Dinesh Kumar; Singh, DevendraA field experiment was conducted during kharif 2015 at experimental farm, Tirhut College of Agriculture, Dholi, (Muzaffarpur) to study the effect of micro and secondary nutrients on growth, yield and quality of blackgram (Vigna mungo (L) Hepper). The experiment was laid-out in a randomized block design (RBD) with eight treatments, each having four replications. The treatments were T0: RDF (control), T1: RDF + B, T2: RDF + Zn, T3: RDF + S, T4: RDF + B + Zn, T5: RDF + B + S, T6: RDF + Zn + S and T7: RDF + Zn + B + S. Uniform basal application was made with 20 kg N ha-1, 40 kg P2O5 ha-1, 20 kg K2O ha-1 through urea, DAP and MOP, respectively. Sulphur, Zn and B were applied @ 20, 5 and 1.5 kg ha-1 from Bentonite-S, Zinc sulphate and Di-sodium tetra-borate pentahydrate, respectively. Plant height at 40 DAS, number of branches plant-1, number of nodules plant-1 at 40 and 50 DAS, number of pods plant-1, number of grains pod-1, test weight, grain yield kg ha-1, straw yield kg ha-1, protein content, gross return, net return and B: C ratio of urdbean significantly affected due to various treatments except plant population, plant height at 20, 60 DAS and at harvest, number of nodules at 60 DAS and harvest index. The higher grain yield (838 kg ha-1) and straw yield (2472 kg ha-1) were obtained due to application of Zn + B + S. Among different treatments, T7 (Zn + B + S) recorded maximum protein content (24.07 %) in grains which was significantly superior over check (20.62 %). After one month incorporation of blackgram biomass (100%) in the respective treated plots, significantly improved the available N, P, Zn and B over control. The higher available N (272.14 kg ha-1), P2O5 (21.7 kg ha-1), Zn (0.85 mg kg-1) and B (0.74 mg kg-1) were analyzed with treatment Zn + B + S while lowest available N (258.25 kg ha-1), P2O5 (15.14 kg ha-1), Zn (0.64 mg kg-1) and B (0.53 mg kg-1) was recorded under control. Higher gross return (67040 ha-1), net return (41940 ha-1) and B: C ratio (1.67) was found with combined application of Zn, B and S.ThesisItem Open Access Integrated Weed Management in Soybean (Glycine maxL.)(Dr. Rajendra Prasad Central Agricultural University, Pusa (Samastipur), 2016) Paudel, Prakash; Singh, R. S.A field experiment entitled “Integrated Weed Management in Soybean (Glycine max L.)” was planned and carried out during Kharif season of 2015 at Agricultural Research Farm of Tirhut College of Agriculture, Dholi, (Muzaffarpur), a campus of Dr. Rajendra Prasad Central Agricultural University, Pusa, Samastipur, Bihar (India) to study the effect of different weed management practices on weeds, crop growth and yield of soybean, to assess the magnitude of yield losses caused by weeds and to work out the economics of weed management practices. The treatments comprised pendimethalin @ 1.0 kg a.i./ha as pre-emergence (T1), imazethapyr @ 100 g a.i./ha at 20 DAS (T2), fenoxaprop-p-etlyl @ 80 g a.i./ha at 20 DAS (T3), quizalofop-p-ethyl @ 50 g a.i./ha at 20 DAS (T4), halosulfuron @ 67.5 g a.i./ha at 20 DAS (T5), pendimethalin @ 1.0 kg a.i./ha as pre-emergence fb imazethapyr @ 100 g a.i./ha at 20 DAS (T6), pendimethalin @ 1.0 kg a.i./ha as pre-emergence fb fenoxaprop-p-ethyl @ 80 g a.i./ha at 20 DAS (T7), pendimethalin @ 1.0 kg a.i./ha as pre-emergence fb quizalofop-p-ethyl @ 50 g a.i./ha at 20 DAS (T8), pendimethalin @ 1.0 kg a.i./ha as pre-emergence fb halosulfuron @ 67.5 g a.i./ha at 20 DAS (T9), pendimethalin @ 1.0 kg a.i./ha as pre-emergence fb hand weeding at 40 DAS (T10), pendimethalin @ 1.0 kg a.i./ha as pre-emergence fb weeding by wheel hoe at 40 DAS (T11), weed free (hand weeding twice at 20 DAS and at 40 DAS) (T12) and weedy check (T13). The treatments were replicated thrice in randomized block design (RBD). The soil of the experimental plot was sandy loam in texture, alkaline in reaction (pH 8.47), low in organic carbon, available N, P2O5 and K2O. The Soybean variety “JS-335” was sown at a spacing of 45 cm× 5 cm using the seed rate of 75 kg/ha by following recommended package of practices. During the course of investigation data on weeds, crop growth, yield parameters and yield were recorded. Weed free situation (hand weeding twice at 20 DAS and at 40 DAS) proved significantly superior in respect of all crop growth parameters and yield attributes among the treatments but was found at par with pendimethalin @ 1.0 kg a.i./ha as pre-emergence fb hand weeding at 40 DAS and pendimethalin @ 1.0 kg a.i./ha as pre-emergence fb quizalofop-p-ethyl @ 50 g a.i./ha at 20 DAS. However, yield obtained under weed free situation (hand weeding twice at 20 DAS and at 40 DAS) (1959 kg/ha) was significantly superior over all other treatment and was closely followed by pendimethalin @ 1.0 kg a.i./ha as pre-emergence fb hand weeding at 40 DAS and pendimethalin @ 1.0 kg a.i./ha as pre-emergence fb quizalofop-p-ethyl @ 50 g a.i./ha at 20 DAS. Highest stover yield and harvest index was also associated with weed free treatment. Weed free situation (hand weeding twice at 20 DAS and at 40 DAS) with significantly higher weed control efficiency resulted into lowest weed population and dry weight of weeds among the treatments. This was closely followed by pendimethalin @ 1.0 kg a.i./ha as pre-emergence fb hand weeding at 40 DAS and pendimethalin @ 1.0 kg a.i./ha as pre-emergence fb quizalofop-p-ethyl @ 50 g a.i./ha at 20 DAS. Weedy check plot recorded significantly highest weed population, weed dry weight and weed index over all other treatments. Reduction in seed yield of soybean due to weed infestation as compared to weed free situation (hand weeding twice at 20 DAS and at 40 DAS) was recorded to the tune of 66.97 %. However, lowest yield loss among the treatments was recorded under pendimethalin @ 1.0 kg a.i./ha as pre-emergence fb hand weeding at 40 DAS (8.22%) which remained statistically at par with pendimethalin @ 1.0 kg a.i./ha as pre-emergence fb quizalofop-p-ethyl @ 50 g a.i./ha at 20 DAS (8.83%). Significantly highest gross return ( 85299.18/ha) among the treatments was realized under weed free situation (hand weeding twice at 20 DAS and at 40 DAS) and was closely followed by pendimethalin @ 1.0 kg a.i./ha as pre-emergence fb hand weeding at 40 DAS and pendimethalin @ 1.0 kg a.i./ha as pre-emergence fb quizalofop-p-ethyl @ 50 g a.i./ha at 20 DAS. Pendimethalin @ 1.0 kg a.i./ha as pre-emergence fb quizalofop-p-ethyl @ 50 g a.i./ha at 20 DAS produced significantly highest net return ( 46890.52/ha) over all other treatments but was found statistically at par with weed free situation (hand weeding twice at 20 DAS and at 40 DAS) ( 44425.18/ha). Pendimethalin @ 1.0 kg a.i./ha as pre-emergence fb quizalofop-p-ethyl @ 50 g a.i./ha at 20 DAS also recorded highest B:C ratio (1.51) among the treatments. Significantly lowest gross returns ( 30225.43/ha), net return ( 2931.43/ha) and B:C ratio (0.11) was recorded under weedy check plot.ThesisItem Open Access Effect of NPK levels on yield and quality of sugarcane varieties under upland rainfed conditions(Dr. Rajendra Prasad Central Agricultural University, Pusa (Samastipur), 2016) Parajuli, Tulsi; Kumar, NavnitA field experiment was conducted during spring season of 2015-16 at Sugarcane Research Institute, Rajendra Agricultural University (presently Dr. Rajendra Prasad Central Agricultural University), Pusa, Bihar to study the effect of NPK levels on yield and quality of sugarcane varieties under upland rainfed conditions. The experiment was laid out in randomized block design (factorial), replicated thrice with five varieties, viz., BO 130, BO 139, BO 153, CoP 9301, and CoLk 94184 tested under three NPK levels, viz., 50, 75 and 100 % of recommended dose. The soil of the experimental site was sandy loam in texture with pH 8.3 and organic carbon 0.43 %. The soil contained 215.3, 23.6 and 143.3 kg/ha available N, P2O5 and K2O respectively. Varieties had significant variation in growth, yield attributes, yield and quality of sugarcane. Germination counts were recorded at 30 and 45 days after planting. Higher germination count was recorded with BO 153 which was followed by CoLk 94184 at both the stages. Experimental data indicated that variety BO 153 produced significantly higher plant population at all the stages of growth which were responsible for higher millable canes at harvest. Variety BO 153 recorded significantly higher LAI at both the stages. Though, BO 139 gave taller plant at all the stages of growth. Similarly, thicker canes (2.44 cm) with maximum single cane weight (812 g) and number of nodes/cane (28.5) was also obtained with BO 139. The maximum cane: top ratio (5.4) was recorded when sugarcane variety CoP 9301 was fertilized with 100 % recommended dose of NPK. Though, it was almost equal (5.4) to the variety BO 153 with 75 % recommended dose of NPK. The maximum brix (21.60 %), pol (18.34 %), juice recovery (64.2 %) and fibre (11.28 %) per cent were computed in variety CoP 9301. BO 153 recorded the maximum cane (66.1 t/ha) and sugar (8.10 %) yield and it was superior over BO 130 and CoP 9301 with 27.1 and 28.6 % more cane yield and 20.7 and 26.6 % more sugar yield, respectively. Results revealed that varieties under evaluation showed significant differences for economics. Variety BO 153 gave the highest net returns (94017 /ha) and B: C ratio (1.26) than rest of the varieties. Among NPK levels, 100 % recommended dose of NPK being at par with 75 % recommended dose of NPK gave higher plant population, LAI and plant height at all the stages of growth except plant height at 210 DAP where with each successive increase in NPK level plant height increased significantly. The number of millable canes increased significantly due to NPK level upto 75 %. However, maximum tillers mortality were noticed at 50 % NPK level and minimum at 100 % recommended dose of NPK. Application of 75 % recommended dose of NPK significantly improved the cane diameter (2.21 cm), length of internodes (8.82 cm), cane: top ratio, brix, pol and CCS percentage as well as TC: TS ratio of sugarcane. Though fibre per cent cane responded significantly upto 100 % recommended dose of NPK. The maximum cane and sugar yield was also obtained with application of 100 % recommended dose of NPK. However, the differences between 75 and 100 % recommended dose of NPK were not significant. Application of 75 and 100 % recommended dose of NPK recorded statistically comparable but significantly higher net returns and B: C ratio over 50 % recommended dose of NPK. Based on yield and economics, sugarcane variety BO 153, fertilized with 75 % recommended dose of NPK is beneficial and effective for upland rainfed conditions in Bihar.
