    NUTRIENT MANAGEMENT INTERVENTIONS IN RICE - RAGI SEQUENCE
    (Acharya N G Ranga Agricultural University, Guntur, 2019) KIRAN KUMAR, SINGUPURAPU; PULLA RAO, Ch
    A field experiment entitled “Nutrient Management Interventions in Rice- Ragi Sequence” was conducted during kharif and rabi seasons of 2017-18 and 2018-19 on sandy loam soil of the Agricultural College Farm, Bapatla. The seven treatments consisted of T1 : 100% RDF (100-60-40 kg N-P-K ha-1) ; T2: 100% RDF+ Soil application of ZnSO4 @ 50 kg ha-1 ; T3: 125% RDF+ Soil application of ZnSO4 @ 50 kg ha-1; T4: 75% RDF+ Poultry manure @ 0.82 t ha1 + Soil application of ZnSO4 @ 50 kg ha-1; T5: 75% RDF+ FYM @ 5.0 t ha-1 + Soil application of ZnSO4 @ 50 kg ha-1; T6: 50% RDF+ Poultry manure @1.6 t ha-1+ Soil application of ZnSO4 @ 50kg ha-1 and T7: 50% RDF+ FYM @ 10 t ha-1+ Soil application of ZnSO4 @ 50 kg ha-1. The experiment was laid out in Randomized Block Design with seven treatments and replicated thrice during kharif rice and in rabi each kharif treatment was sub divided into four sub treatments and hence, The split plot design was adopted in rabi. Total No. of plots per each replication in the rabi was 28 (7x4= 28). The results indicated that, increased levels of organic and inorganics had a significant influence on increased plant height and drymatter production. Application of 50 % RDF + FYM @ 10 t ha-1 + ZnSO4 @ 50 kg ha-1 recorded the highest plant height and drymatter production consistently at 30 DAT, 60 DAT, 90 DAT and harvest stages of kharif rice. During rabi ragi, the residual fertility and fertiliser levels had a significant influence on the plant height during both the years of study. Among the fertilizer levels S2 (100% RDF) recorded highest plant height and drymatter production of ragi in the both the years of study and in pooled data. xx Number of tillers m-2 differed significantly among the treatments. The highest number of tillers m-2 at all the growth stages of both the crops (kharif rice and rabi ragi) were recorded with 50 % RDF + FYM @ 10 t ha-1 +ZnSO4 @ 50 kg ha-1 in kharif and 100 % RDF in rabi respectively. No. of leaves, chlorophyll content and LAI of rice at different phenophases were highest with the application of 125 % RDF along with 50 kg ZnSO4 ha-1 All the yield attributes viz., number of productive tillers m-2, total number of grains panicle-1, filled grains panicle-1, test weight (g/1000 grain), spikelet sterility, grain, straw yield and harvest index were significantly influenced by different treatments. Highest number of productive tillers m-2, total number of filled grains panicle-1, grain, straw yield with T7 treatment. Significantly highest test weight was recorded with T7 treatment. However, this was remained on par with T3. All the quality parameters, cooking quality and milling quality of rice did not differ significantly among the treatments in rice during both the years of study. Nutrient content and uptake of nitrogen, phosphorus, potassium and zinc have increased significantly with the fertility levels and organics. 50 % RDF+ FYM @ 10 t ha-1 + ZnSO4 @ 50 kg ha-1 recorded the highest nitrogen, phosphorus, potassium and zinc contents at different growth stages and in grain and straw of rice. Post harvest available soil N, P, K and zinc status in the soil was recorded higher with the treatments received both organics and inorganics. The highest gross returns and net returns were recorded due to the application of 50 % RDF+ FYM @ 10 t ha -1 + ZnSO4 @ 50 kg ha-1. Among all the treatments, highest returns per rupee investment was also obtained with the application of 50 % RDF+ FYM @ 10 t ha -1 + ZnSO4 @ 50 kg ha-1 (T7). Lowest bulk density after harvest of the rice crop was recorded with all the organic manured plots. However, all the seven treatments were remained on par with one and another. In rabi ragi, all the growth parameters like plant height, No. of tillers and drymatter production at different growth stages were recorded the highest in the sub treatment, S2 which received 100 % RDF. Yield attributes and yield of ragi was also followed similar trend during both the years of study and all these parameters were recorded significantly the highest with 100 % RDF (S2) over the rest treatments. The sub treatments S3 (75 % RDF) and S4 (50 % RDF) were remained on par with each other. Nutrient content and uptake of N,P,K and Zn by ragi crop at all the growth stages including grain and straw were found to be significantly superior with 100 % RDF (S2) to the rest of the treatments. xxi Highest gross returns, net returns and returns per rupee invested were obtained with T7S2 which received 50 % RDF+ FYM @ 10 t ha-1 + ZnSO4 @ 50 kg ha-1 as residual treatment and 100% RDF as fertilizer level to the succeeding ragi under no-till condition. From the above, it can be concluded that application of application of 50% RDF through inorganic fertilizer + FYM @10 t ha-1 + ZnSO4 @ 50 kg ha-1 closely followed by 125% RDF+ ZnSO4 @ 50 kg ha-1 recorded higher growth, yield parameters, grain and straw yields and nutrient uptake of kharif rice in both the years of study. While, fertilizer levels in rabi ragi, 100 % RDF (30-30-20 kg NPK ha1) was recorded higher growth, yield parameters, grain and straw yields, nutrient uptake and more economical during the both the years of experimentation and in pooled data as well.

    EFFECT OF PHOSPHORUS MANAGEMENT ON YIELD AND QUALITY OF FINGERMILLET [Eleusine coracana (L.)]
    (Acharya N.G. Ranga Agricultural University, Guntur, 2016) KIRAN KUMAR, SINGUPURAPU; PULLA RAO, Ch
    A field experiment entitled “Effect of Phosphorus management on yield and quality of fingermillet [Eleusine coracana (L.)]” was conducted during kharif, 2015 on sandy soil of the Agricultural College Farm, Bapatla. The treatments consisted of T1 : Recommended dose of phosphorus (RDP) @ 30 kg P2O5 ha-1; T2 : 75% Recommended dose of inorganic phosphorus + FYM 3.75 t ha-1; T3 : 75 % Recommended dose of inorganic phosphorus + Vermicompost @ 0.75 t ha-1; T4 : 50 % Recommended dose of inorganic phosphorus + FYM 7.5 t ha-1; T5 : 50 % Recommended dose of inorganic phosphorus + Vermicompost @ 1.5 t ha-1; T6 : T1 + PSB @ 5.0 kg ha-1; T7 : T4 + PSB @ 5.0 kg ha-1; T8 : T5 + PSB @ 5.0 kg ha-1 and T9 : No phosphorus. The experiment was conducted in a randomized block design (RBD) and replicated thrice. Increased levels of organic manures and chemical phosphatic fertilizers in combination with biofertilizer (PSB) had a significant influence on increased plant height and drymatter production. Application of 50 % Recommended dose of phosphorus + FYM @ 7.5 t ha-1 + PSB @ 5.0 kg ha-1 recorded the highest plant height (53.0 cm) and drymatter production (566.0 kg ha-1) consistently at 30 DAS, 60 DAS and harvest stages. Number of tillers m-2 differed significantly among the treatments. Number of tillers m-2 increased slightly from 30 DAS to 60 DAS and remained constant thereafter except for T7, T8 and T1 treatments. At 30 DAS, significantly highest number of tillers m-2 was recorded in T7 treatment (67.0) and, it was on par with T8 (64.6). At 60 DAS and at harvest T7 treatment recorded the highest number of tillers m-2 72.7 and 74.3 respectively. Days to 50% flowering of fingermillet was significantly reduced with increasing levels of organic manures along with biofertilizer PSB. The control (T9) recorded maximum number of days to 50% flowering (75.0) where as the lowest number of days to 50% flowering was recorded with T7 and T8 treatments (68.0) followed by T2 and T5 treatments (70.0). There was a difference of seven days between the highest and the lowest number of days to 50% flowering within the treatments. All the yield attributes viz., number of earheads m-2, length of earhead (cm), number of fingers earhead-1, number of filled grains finger-1 and test weight (g/1000 grain) were significantly influenced by different treatments. Highest number of earheads m-2 (62.0), length of earhead (8.0 cm), and number of filled grains finger-1 (161.0) and number of fingers per earhead (8.3) were recorded with T7 treatment which was on a par with T8 treatment. Significantly highest value of test weight was recorded with T7 treatment (3.0 g/1000 grains) followed by T8, T4, T5 treatments (2.87, 2.73 and 2.70 g/1000 grains, respectively) and found to be significantly superior to control. Grain and straw yields of fingermillet differed significantly with varying levels of organic and inorganic fertilizers in association with biofertilizer (PSB). The maximum grain yield (2200 kg ha-1) and straw yield (4550 kg ha-1) was recorded with the combined application of inorganic and organic fertilizer and PSB (50 % Recommended dose of phosphorus + FYM @ 7.5 t ha-1 + PSB @ 5.0 kg ha-1) but, it remained on par with 50 % recommended dose of phosphorus+ vermicompost @ 1.5 t ha-1 + PSB @ 5.0 kg ha-1. The magnitude of increase in grain yield with T7 (2200 kg ha-1), T8 (1951 kg ha-1) and T4 treatments (1678 kg ha-1) over control (800 kg ha-1) was to the tune of 175, 143.8 and 109.7 per cent, respectively. Application of phosphorus alone recorded higher grain (900 kg ha-1) and straw (2800 kg ha-1) yields over the control (800 kg ha-1 & 2650 kg ha-1 respectively) which was 12.5& 5.6 percent higher over the control. The highest harvest index (32.5%) was recorded with the application of 50% recommended dose of phosphorus + FYM @ 7.5 t ha -1 + PSB @ 5.0 kg ha-1 followed by T8 treatment (31.5%) which were on par with rest of the treatments except control. Highest phosphorus use efficiency (46.6) was also recorded with T7 followed by T8 (38.4). Protein content in fingermillet grain was significantly influenced by varying P levels in association with organic and biofertilizer (PSB). Maximum protein content in grain was recorded in the T7 treatment (12.2%) followed by T8 treatment (11.0%). The treatments T4, T2 and T5 also recorded significantly higher protein content over control. Nutrient content and uptake of nitrogen, phosphorus, potassium, calcium and iron increased significantly with the fertility levels. 50 % recommended dose of phosphorus + FYM @ 7.5 t ha -1 + PSB @ 5.0 kg ha-1 recorded the highest nitrogen, phosphorus, potassium, calcium and iron content in grain and straw of finger millet. The highest nitrogen, phosphorus, potassium, calcium and iron uptake by grain and straw were recorded with T7 treatment which was on par with T8 but significantly superior to control and application of phosphorus alone. Post harvest available N, P and K status in the soil was recorded with higher organic manure treatments T4, T2, T5 and T3. The highest gross returns ( 28675 ha-1) and net returns ( 18209 ha-1) were recorded by the application of 50 % Recommended dose of phosphorus + FYM @ 7.5 t ha -1 + PSB @ 5.0 kg ha-1 (T7) followed by 50 % Recommended dose of phosphorus+ Vermicompost @ 1.5 t ha-1 + PSB @ 5.0 kg ha-1 (T8). Lowest gross returns ( 10925) and net returns ( 4747ha-1) were recorded with control (T9). Application of phosphorus alone recorded gross returns of 12200 and net returns of 5606 ha-1. Among all the treatments, highest returns per rupee investment (1.73) was obtained with the application of 50 % recommended dose of phosphorus + FYM @ 7.5 t ha -1 + PSB @ 5.0 kg ha-1 (T7) followed by T8 i.e. 50 % recommended dose of phosphorus + Vermicompost @ 1.5 t ha -1 + PSB @ 5.0 kg ha-1 (1.38). It is concluded that application of application of 50 % recommended dose of phosphorus + FYM @ 7.5 t ha -1 + PSB @ 5.0 kg ha-1 was more economical in obtaining higher returns per rupee investment and gave higher growth, yield parameters, grain and straw yields of fingermillet.
