The field experiments were conducted to study the residual effect of nutrient management practices of kharif rice on growth and yield of rabi greengram was conducted at Krishi Vigyan Kendra, Balasore Odisha during rabi 2013−14 and 2014−15. The experiment was laid out in RBD during the kharif season with 12 treatments replicated thrice and rabi greengram was grown in the residual fertility in the plots without disturbing the layout. The residual effect of different nutrient management prcatices applied to kharif rice significantly influenced the growth, yield attributes and yield of rabi greengram. Growth attributes viz. Plant height, number of branches, dry matter accumulation and number of nodules per plant showed significant improvement due to combined application of nutrients from organic and inorganic sources. Application of 75% N through chemical fertilizers along with 25% N through vermicompost to preceding kharif rice had significant residual effect on rabi grrengram and recorded significantly higher seed yield (959 kg ha-1) and stover yield (2753 kg ha-1).

Aims: To evaluate the influence of farmyard manure, vermicompost, mustard oil cake, poultry manure, and inorganic fertilisers (N, P, K) on maize dry matter buildup and nutrient uptake by plants, as well as to demonstrate how maize may be produced in a poplar agroforestry system. Study Design: Randomized block design. Place and Duration of Study: Forest Nursery, College of Forestry, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, Uttar Pradesh, India, between July 2019 – October 2019 and  July 2020 – October 2020. Methodology: The research was laid out in Randomized Block Design replicated thrice with twelve treatments viz., T1 (Control), T2 (100% Recommended dose of fertilizer), T3 (75%) RDF), T4 (50%) RDF), T5 (75%) RDF + (25%) RDF through FYM), T6 (50%) RDF + (50%) RDF through FYM), T7 (75%) RDF + (25%) RDF through Mustard Oilcake, T8 (50%) RDF + (50%) RDF through Mustard Oilcake and T9 (75%) RDF + (25%) RDF through Vermicompost, T10 (50%) RDF + (50%) RDF through Vermicompost, T11 (75%) RDF + (25%) RDF through poultry manure and T12 (50%) RDF + (50%) RDF through poultry manure. These treatment combinations were applied prior to sowing of maize. After harvesting of maize in October, the said observations i.e. dry matter accumulation and nutrient uptake by maize plant were calculated. Results: In the effect of twelve treatments, T9 (75% RDF + 25% N through Vermicompost) considerably influenced and recorded highest dry matter accumulation and nutrient uptake by maize, followed by T11 during two consecutive years, while T1 (control), where no fertiliser or manure was applied under a poplar agroforestry system, recorded the lowest. Conclusion: by application of vermicompost in combination with chemical fertiliser considerably improved growth characteristics and output. All of the treatments had a considerable impact on maize growth and yield. The optimum result was found to be 75 % RDF + 25 % Vermicompost (T9) in the current study. Our results indicated that, organic fertilizer can be a superior supplement of inorganic fertilizer to produce healthier growth and yield of maize.
