Integrated farming system (IFS) ensures efficient utilization of available farm resources, increases unit productivity and income that are pre-requisite for sustainable livelihood of small and marginal farmers. The present study was conducted to evaluate the performance of four IFS model developed in ~ 1.0 acre area, at ICAR Research Complex for North Eastern Hill Region, Nagaland Centre, Jharnapani, Medziphema, Nagaland. The major components in IFS models were agriculture, horticulture, livestock and subsidiary components like fishery, vermicompost, mushroom and azolla. The field crops, vegetables and livestock components were included in IFS model considering topography of land, soil texture and preference for the tribal livelihood. The performance in terms of component wise productivity, profitability, employment generation and sustainability value index (SVI) were evaluated in consecutive three years (2012–2015). The combinations of subsidiary components in agriculture + horticulture + poultry + fishery in IFS model (model–4) gave the highest net returns (Rupees 32040) followed by the model with agriculture + horticulture + fishery + piggery + vermicompost (model 3) with net profits of Rupees 21230. In field crops component, cropping sequence of ricetoria- mungbean system was found to be the best in terms of productivity among the tested IFS models except in model 1. In terms of employment generation, IFS model-4 has shown maximum man-days engagement (395 days), followed by 350 days in model-3. Based on sustainability values index (SI) derived from different IFS models, maximum SVI values was recorded in model-4 (0.71) followed by model-3 (0.47). Therefore, the intensification of IFS model with crop, horticulture, fishery and livestock or poultry should be popularized among the small and marginal farmers on a larger scale, as it provide scope for higher returns, year round employment and sustainable livelihood in longer perspectives of Eastern Himalayas.

A field experiment was conducted to investigate the effect of integrated nutrition along with application of micronutrient and biofertilizers on productivity and profitability of french bean (Phaseolus vulgaris L.) at the ICARRC for NEH Region, Nagaland Centre, Jharnapani, during rabi 2013–15. Treatment consisted of four nutrition levels, viz. control, 100% RDF (80-60-30-20 kg NPKS/ha), 100% RDN (RDN:80 kg/ha through 16 t/ha of FYM), 75% RDF + 25% RDN and 100% RDF + 25% RDN in main-plot and five levels of biofertilizers + micronutrient, viz. control, PGPR (Rhizobimum + Bacillus + Pseudomonas), PGPR + 5 kg Zn/ha, PGPR + 1.5 kg Mo/ha and PGPR + 5 kg Zn + 1.5 kg Mo/ha in sub-plot. Experiment was laid out in split-plot design and replicated thrice. Significantly higher seed yield (1630 kg/ha) was recorded with application of 100% RDF + 25% RDN, which was 30% higher over 100% RDN. Maximum net returns (₹ 21399/ha), B:C ratio (1.31), production efficiency (15.8 kg/ha/day) and economic efficiency (₹ 305/ha/day) were noted with 100% RDF + 25% RDN. Maximum grain yield (1551 kg/ha) had recorded with PGPR +5 kg Zn ha+1.5 kg Mo/ha. Maximum net returns (₹ 29941/ha), B:C ratio (1.30), production efficiency (15.1 kg/ ha/day) and economic efficiency (₹ 210/ha/day) were also noted with PGPR+5 kg Zn ha + 1.5 kg Mo/ha. Thus, to achieve the higher productivity and profitability, french bean could be grown with 100% RDF+25% RDN through organic manures (FYM) and seed inoculation with PGPRs + micronutrient in foot hill condition of Eastern Himalayas.

Field experiment was conducted during rabi 2013-14 and 2014-15 to study the effect of paper mill waste integrated nutrition on yield, economics and soil health of garden pea varieties at ICAR-Research Complex for NEH Region, Nagaland Centre, Jharnapani, Nagaland. The experiment was laid out in split plot design and replicated thrice. Maximum seed yields (905 kg/ha), green pod yields (3454 kg/ha), gross return (₹ 108372/ha), net return (₹ 60260/ha) and B: C ratio (2.25) had recorded with Azad pea. Application of paper mill waste @ 1.0 t/ha gave higher yield attributes of garden pea than to its lowers levels. Highest gross return (₹109189/ha) and net return (₹ 57977/ha) was obtained with paper mill waste @ 1.0 t/ha, however the maximum B: C ratio (2.20) was noted in 0.5 t/ha. Significantly higher seed yield (926 kg/ha) and green pod yield (3449 kg/ha) were recorded with application of 100% RDF+25% RDF (ON), which was 53, 13, and 45% higher, respectively over control. Among integrated nutrition, maximum seed yield (977 kg/ha), green pod yield (3646), gross return (₹ 115328/ha), net return (₹ 64616/ha) and B:C ratio (2.28) was noted with 100% RDF + 25% RDF (ON). Soil health attributes, i.e. pH, EC, soil organic carbon; available NPK had improved significantly due to integrated nutrition. Thus, Azad pea could be grown with application of paper mill waste @ 1.0 t/ha along with 100% RDF+25% RDF(ON) for better productivity, profitability and soil health in Eastern Himalayas.

An experiment was conducted during 2013-15 at Research Farm, ICAR Research Complex for NEH Region, Nagaland Centre, Jharnapani, Nagaland to evaluate thirty two landraces of rajma bean for the growth, yield and quality under low altitude conditions of Nagaland. The experiment was laid out in randomized complete block design with three replications. Eighteen traits viz., growth, yield related components and four quality parameters were recorded. Significant variations were observed for all the traits studied among the landraces evaluated. The results revealed that the line RCN 11 and RCN 20 performed better under lower altitude conditions of Nagaland. The RCN 11 and RCN 20 have recorded the highest seed yield of 63.8 g/plant. The maximum 100-seed weight was recorded by RCN 11 (60.0g) and RCN 20 (56.2 g). The highest yield of 1766.1 and 1766.8 kg/ha was recorded by RCN 11 and RCN 20 respectively. RCN 6 recorded highest protein content of 20.1 % and this line also registered 49.3 g/plant seed yield and 1256.4 kg/ha yields.

The pineapple var. Kew was planted on black polythene film mulching with double hedgerow planting to find out the influence of mulches on soil and plant. The soil samples were collected twice (kharif and rabi) at two different depths (0-15 and 15-30 cm), and the pH, soil organic carbon (SOC), nitrogen, phosphorus, potassium, basal respiration and soil microbial biomass carbon were analysed. The data revealed that soil organic carbon and available N, P, and K content were slightly higher in the bottom hill than the top hill. The mulched field had higher nutrients than the non-mulched field. The fertility level varied slightly between the seasons. The biological parameters (microbial biomass carbon) were observed to be significantly higher (P≤0.05) in the bottom hill in both the seasons than the non-mulched field. The soil moisture content ranged from 5.9 % in March to 24.24 % August in the bottom hill (15-30 cm depth). The moisture content in the non-mulched field was lower than the mulched field.
