A field experiment was conducted during kharif 2011 on experimental farm of the College of Post Graduate Studies (CAU–Imphal), Umiam (Meghalaya) to evaluate the effect of integration of green manuring, FYM and fertilizers as integrated nutrient management (INM) practices on growth and developmental behaviour of quality protein maize cultivar QPM 1. The data revealed that comparatively higher amount of primary nutrients were added in green manured maize plots in comparison to non green manured treatments. Green manuring also left a positive response on plant height, CGR, RGR leaf area, and dry matter accumulation in plants though the difference between green manured and non-green manured treatments was at par. Treatments 75 % RDF + 5 t FYM ha-1, 50 % RDF + 7.5 t FYM ha-1, 100 % RDF ha-1 and 75 % RDF + 2.5 t FYM ha-1 recorded significantly higher values of all the above said growth parameters over 50 % RDF + 5 t FYM ha-1 and control treatments. At all stages of observations, the maximum dry matter was associated with RDF (recommended doses of fertilizers) which was at par with 75 % RDF + 5 t FYM ha-1, but significantly higher over the plant dry weight recorded from all remaining treatments. A Significant difference in CGR at 30 – 60 and 60 – 90 DAS stage and in RGR at 90 DAS - harvest stage was observed due to various combinations of recommended dose of fertilizer with different doses of FYM. Number of days taken to attain the stages of 50% tasselling, silking and maturity did not differ significantly due to green manuring. However, treatment 75 % RDF + 5 t FYM ha-1 took significantly lesser number of days for these stages than other treatment combinations. The superiority of the treatment 75 % RDF + 5 t FYM ha-1 indicated a possibility of substituting 25% of RDF with 5 t FYM ha-1 without any loss in dry matter accumulation in plants of the quality protein hybrid maize in mid-hill ecosystems of Meghalaya.

A field experiment was carried out during summer season of 2018 at Instructional Farm, Jaguli, BCKV, West Bengal to study the effect of integrated nutrient management on growth, yield and economics in hybrid maize. The treatments were T1-100% RDF (150:75:75 kg/ha N, P2O5 and K2O) (control), T2- 75% RDF+ Vermicompost @ 2t/ha, T3-75% RDF+ Yeast Vinasse @ 2t/ha, T4-75% RDF+ Vermicompost @ 2t/ha+ soil application of ZnSO4 @ 25 kg/ha, T5-75% RDF+ Yeast Vinasse @ 2t/ha+ soil application of ZnSO4 @ 25 kg/ha, T6-75% RDF+ Vermicompost @ 2t/ha+ Foliar application of ZnSO4 @ 0.5% and T7-75% RDF+ Yeast Vinasse @ 2t/ha+ Foliar application of ZnSO4 @ 0.5% replicated thrice in RBD. The result of the experiment revealed that application of vermicompost @ 2 t/ha along with 75% RDF and 0.5% foliar application of ZnSO4 (T6) exhibited maximum plant height (250.97 cm), LAI (4.58), dry matter accumulation (1680.38 g/m2), number of grains/cob (402.64), cob length (22.34 cm), grain yield (9.04 t/ha), stover yield (13.50 t/ha), net return (Rs.77112/ha), BCR (2.33) and uptake of N, P2O5 and K2O (200.54, 66.45 and 119.12 kg/ha respectively) over application of 100% RDF. However, T6 was statistically at par with the T4 and T7, which produced 8.94 and 8.75 t/ha grains respectively. Therefore, the study concluded that integrated application of vermicompost @ 2 t/ha along with 75% RDF and 0.5% foliar application of ZnSO4 can be recommended for better grain yield and higher profit of summer maize.

SUMMARYThe distribution of dry matter among the fractions of cotton boll (the bur, the fibre and the seed) may have significant impact on fibre biomass per boll, and consequently on lint yield. Little is known on how cotton boll allocates available photosynthetic assimilates to its components. A two-year field study was conducted to ascertain the difference in boll dry matter production and partitioning among three cotton genotypes differing in boll size and lint percentage. The dynamics of dry matter production in all fractions of cotton boll against boll age followed a logistic pattern. The final dry weights of all components were largely due to the duration of dry matter exponential accumulation, and less correlated with the maximal rate of exponential accumulation. Partitioning biomass to the bur differed significantly among these genotypes at 10 days post-anthesis (DPA). The genotypic difference in partitioning biomass to the fibre was originally observed at 24 DPA in 2009, while in 2010, this was observed at 17 DPA. The genotypic difference emerged rather late for the seed ratio compared with the fibre ratio and the bur ratio, which was first observed at 45 DPA in 2009 and at 31 DPA in 2010. These results indicate that management practices may need to be applied to cotton plants prior to 31 DPA to ensure optimal boll size and partitioning. Large boll genotype MM-2 consistently maintained higher seed ratio and lower fibre ratio than two other genotypes (2870 and AX) due to more developing ovules in its boll. These differences contributed to significant difference in lint percentage and less difference in fibre mass per boll between MM-2 and 2870 and AX.

A field investigation was carried out during Rabi season (Pishanam rice) of 2012-2013 at wetland of Central Farm, Agricultural College and Research Institute, TNAU, Killikulam, to study the effect of integrated nutrient management practices on dry matter production, yield and NPK uptake of transplanted rice. The treatments were laid out in a Randomized Block Design and replicated thrice using the rice variety ADT(R) 45. Among the different integrated nutrient management practices, application of GLM @ 6.25 t ha-1 + Azophosmet + 100 % NPK registered significantly the highest (P<0.01) dry matter production at all the stages (Active tillering; 1690, flowering; 9100 and harvest;14490 kg ha-1). The grain yield was increased, when GLM was integrated with 100 % NPK application (6030 kg ha-1). The grain yield was further increased, when Azophosmet was applied through seed and soil application along with GLM and 100 % NPK (6617 kg ha-1). However, it was on par with application of FYM + Azophosmet + 100 % NPK. The same trend was noticed in straw yield also. The uptake of N, P and K nutrients by rice crop at har-vest stages (95.6, 37.7 and 118 kg ha-1) of crop growth was remarkably increased by the application of GLM + Azophosmet + 100 % NPK. Among the various nutrient management practices, application of GLM + Azophosmet + 100 % NPK registered superior growth indicators due to the effective utilization of various nutrients and subsequent accumulation of more assimilates which inturn led to improved vegetative growth and higher yield of transplanted rice.

Background: Integrated nutrient management is considered as one of the major tools in agricultural production worldwide. Occupying 3.5% of gross cropped area (GCA), maize accounts for 2.3% of total fertilizer consumption. Despite its soil status, little is known about the application and dosage of integrated nutrient in the experimental hybrid maize crop in the region. Any strategy against this nutrient deterioration must have a good knowledge of the composition and application of integrated nutrient source utilized. The field study aimed to study the integrated nutrient management in hybrid maize of this region to evaluate the performance in growth, yield and nutrient related problems.Methods: A Field experiment was conducted during rabi season of 2018, at experimental farm, Department of Agronomy, Annamalai University, Chidambaram, Tamilnadu. India. Thirteen treatments with three replications were laid out in randomized block design. The treatments combinations were T1: Recommended dose of fertilizer (RDF) 135:62.5:50 kg N:P2O5:K2O ha-1, T2: RDF + Beema green granules (25 kg ha-1) as soil application, T3: 75% RDF + Beema green granules (25 kg ha-1) as soil application, T4: RDF + Uphaar (250gm ha-1) as foliar spray twice, T5: RDF + Beema green granules (25 kg ha-1) soil application + Uphaar (250gm ha-1) foliar spray twice, T6: 75% RDF + Beema green granules (25 kg ha-1) soil application + Uphaar (250gm ha-1) foliar spray twice, T7: RDF + Tracel (3.75kgha-1) foliar spray twice, T8: RDF + Beema green granules (25 kg ha-1) soil application + Tracel (3.75kg ha-1) foliar spray twice, T9: 75% RDF + Beema green granules (25 kg ha-1) soil application + Tracel (3.75kg ha-1) foliar spray twice, T10: RDF + Uphaar (250gm ha-1) first and Tracel (3.75kg ha-1) second foliar spray. T11: RDF + Beema green granules (25 kg ha-1) soil application + Uphaar (250gm ha-1) first and Tracel (3.75kg ha-1) second foliar spray, T12: 75% RDF + Beema green granules (25 kg ha-1) soil application + Uphaar (250gm ha-1) first and Tracel (3.75kg ha-1) second foliar spray, T13: RDF + water spray twice. The collected samples were statistically analyzed for cob length, cob diameter, grain no. /cob, grain yield, stover yield, available Nitrogen, Phosphorus and Potassium and Post-harvest nutrient status of Nitrogen, Phosphorus and Potassium. Result: Our investigation in the maize hybrid crop has confirmed us with unique results. Among the treatments RDF + Beema green granules (25 kg ha-1) soil application + Uphaar (250gm ha-1) first and Tracel (3.75kg ha-1) second foliar spray (T11) was highly significant with increased yield and yield attributes and was best in gross and net returns too. The present work will be a contribution to the comprehensive study of the integrated nutrient management in hybrid maize.

A field experiment was conducted at Instructional-cum-Research (ICR) Farm, Assam Agricultural University, Jorhat-13 during autumn season of 2015 to study the nutrient management of direct seeded autumn rice under various irrigation schedules. The experiment consisted of four irrigation schedules viz., I1(No irrigation), I2(Irrigation at tiller initiation (TI) + boot leaf stage (BL)), I3(Irrigation at TI + panicle initiation (PI) + BL), I4 (Irrigation at TI + PI + Grain filling stage(GF)) and three nutrient management practices viz.,F1(100 % RDF +2t/ha FYM), F2(50 % RDF +1.5 t/ha enriched compost), F3(50 % RDF + 1.5 t/ha Vermicompost). The trial was laid out in split plot design with three replications. The soil was sandy loam. Inglongkiri rice variety was used in the experiment. Results revealed that irrigation schedule I3(Irrigation at TI + PI + BL) recorded significantly the highest growth characters of rice in terms of plant height, number of leaves per plant, and dry matter accumulation. Different nutrient management practices brought about significant differences in plant population per and dry matter accumulation. The highest of these parameters were recorded under application of 50% RDF along with 1.5 t/ha enriched compost and this was statically at par with F1 (100% RDF +2 t/ha FYM).

AbstractDetermination of the optimal fertilization method is crucial to maximize nitrogen use efficiency and yield of different rice cultivars. Side-deep fertilization with controlled-release nitrogen, in conjunction with machine transplanting and subsequent topdressing, was applied to Indica–japonica hybrid rice ‘Yongyou1540’ (YY1540) and indica hybrid rice ‘Tianyouhuazhan’ (TYHZ). Four nitrogen treatments were applied in 2018 and 2019: traditional nitrogen application with quick-release nitrogen (T1), single-dose deep fertilization at transplanting with 100% controlled-release nitrogen (T2), and deep fertilization of 70% controlled-release nitrogen and topdressing of 30% quick nitrogen at tillering (T3), or at panicle initiation (T4). Side-deep fertilization reduced the fertilizer application frequency without causing yield loss, T4 enhanced the yield of YY1540 by increasing the number of productive tillers and number of spikelets per panicle compared with T1, T2 and T3. The yield of TYHZ showed no significant difference among treatments. The T4 treatment decreased the number of tillers at the tilling peak stage and increased the percentage productive tillers and number of differentiated spikelets. Compared with the other treatments, T4 increased dry matter accumulation and leaf area index during panicle initiation and grain ripening, and contributed to enhanced nitrogen uptake and nitrogen utilization in YY1540. On average, nitrogen uptake and utilization in YY1540 were highest in T4, but no significant differences among treatments were observed in TYHZ. Dry matter accumulation and nitrogen uptake from panicle initiation to heading of YY1540 were correlated with number of spikelets per panicle, but no significant correlations were observed for TYHZ. Supplementary topdressing with quick-release nitrogen at the panicle initiation stage was required to increase yield of indica–japonica hybrid rice, whereas single-dose deep fertilization with controlled-release nitrogen is satisfactory for the indica hybrid cultivar.
