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.

A field experiment was conducted during kharif season (June to September) of 2013 and 2014 at research farm of Regional Research and Technology Transfer Sub-station, Kirei, Sundergarh, Odisha University of Agriculture and Technology of Odisha, India which is located in the geographic parallels of 220 4’ N and 840 2’ E. The objective of the experiment is to find out the most efficient and economic combination of different organic and inorganic sources of nutrients to increase the growth, productivity and economics of hybrid maize without deteriorating the soil qualities. The experiment comprised of eight treatments, namely 100% Recommended dose of N, P2O5 and K2O, 75% Recommended dose of fertilizer (RDF) nitrogen+25% N through vermicompost, 75% RDF nitrogen+25% N through mustard oil cake, 75% RDF nitrogen+25% N through Farmyard manure, 50% RDF nitrogen+50% N through vermicompost, 50% RDF nitrogen+50% N through mustard oil cake, 50% RDF nitrogen+50% N through Farmyard manure, Control (no manure no nitrogen). Integrated application of 75% Recommended DFN+25% N through vermicompost resulted significantly highest plant height (220.8 cm) at harvest, highest leaf area index (5.15) at 60 days after sowing, dry matter accumulation at harvest (1745 g m-2), number of grains cob-1 (466.49), Grain weight cob-1 (102.67), test weight (220.30 g 1000 grain-1), length of cob (24.25 cm), girth of cob (18.01 cm), number of cobs plant-1 (1.07), maize grain yield of 6.79 t ha-1, Stover yield (10.95 t ha-1 ), harvest index (0.39), gross return (` 88,318 ha-1), net return (` 52,099 ha-1), return rupee-1 invested (` 2.44).

Poor nutrient management is one of the key factors contributing to decline in the productivity of maize in Nepal. Few studies have been done on developing site and variety specific fertilizer recommendation. Therefore, a field experiment was conducted at National Maize Research Program (NMRP) Rampur, Chitwan during winter season in September 2016 to study the response of hybrid maize (RML95/RML96) to different doses of soil application of nitrogen (N) and phosphorous (P). The treatments included were 120:60, 120 :( 40+20), 160:60, 160 :( 40+20), 200:60, 200 :( 40+20), 240:60, and 240 :( 40+20) N: P kg ha-1. Potassium fertilizer was fixed and applied as per the Government recommendation i.e., 40 kg K ha-1.Eight treatments were replicated three times in randomized complete block design and maize was planted in six rows of four meter long plot. The research findings revealed that each level of N significantly increased grain yield up to 240 kg N ha-1. The grain yield (8.8 t ha-1) obtained under 240 kg N ha-1 was significantly higher than that obtained under 120,160 and 200 kg N ha-1. However, the results revealed that split application of P failed to bring about any significant difference in the grain yield as well as yield parameters of maize. We can, thus conclude that the addition of increasing rate of N increases the yield and yield attributing characters of maize.  Int. J. Appl. Sci. Biotechnol. Vol 5(4): 537-541

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.
