A study was carried out to assess the effect of intercrops and integrated nutrient management on yield, quality and nutrient uptake of chilli during 2015-16 at College of Horticulture, Venkataramannagudem. Impact of four intercrops i.e onion (M1), coriander (M2), fenugreek (M3) and marigold (M4) combined with five INM treatments viz., 100% RDN through urea (S0), 25% RDN through FYM + 75% RDN through urea (S1), 25% RDN through vermicompost + 75% RDN through urea (S2), 25% RDN through poultry manure + 75% RDN through urea (S3) and 25% RDN through neem cake + 75% RDN through urea (S4) on performance of the chilli was studied.. It was found that intercrops and INM treatments showed significant influence on yield, quality and nutrient uptake of chilli. Chilli intercropped with fenugreek (M3) treatment recorded maximum values for yield, quality and nutrient uptake in chilli, whereas, chilli with marigold (M4) treatment recorded the minimum values for all the parameters. INM treatments found superior over 100% RDN through inorganic fertilisers. Application of 25% RDN through neem cake + 75% RDN through urea (S4) treatment recorded the highest values for all the parameters. Among the interactions, the chilli, intercropped with fenugreek and applied with 75% RDN through urea + 25% RDN through neem cake (M3S4) was found superior among all the treatments.

Attention to intercropping for sustainable agriculture is increasing, and scientific studies on intercropping have also grown in recent years. Agroforestry Systems, which combine annual crops with trees, are used widely in semiarid regions to reduce wind erosion and improve the efficiency of resources such as water and nutrients. Field experiments were conducted at Tamil Nadu Newsprint and Papers Limited Farm, Mondipatty, Tamil Nadu, to study the compatibility of intercropping systems in the Dalbergia sissoo-based Horti-silvicultural system for two years during 2016 and 2017. The experiments were conducted in a split-plot design with four replications.The main plot treatments were M1: Cassava M2:Chillies and the subplot treatments were five nutrient management packages viz., S1: Untreated control, S2: 100 % Recommended Dose of Fertilizers (Cassava: 90: 90: 240 and Chillies: 60: 80: 80),S3: 125 % Recommended Dose of Fertilizers (Cassava: 112.5: 112.5: 300 and Chillies: 75: 100: 100),...

A field experiment was conducted during Kharif season-2017 and 2018 at Agriculture and Horticultural Research Station, Bavikere. The experiment was laid out in Randomized Complete Block Design with seven treatments and three replication. Maize is grown in paired row of 75/45 cm × 30 cm while pole bean crop was made to grow besides single row of maize in paired row system with 120 cm × 30 cm. Thereby, the whole system had 55,000 and 27,777 population respectively for maize and pole bean. In this system, application 100 per cent RDF of maize (100:50:25 N, P and K kg ha-1) supplied to both the crops (T1) and application 100 per cent RDF of pole bean (63💯75 N, P and K kg ha-1) supplied to both the crops (T2) were tested against, five different combinations of fertilizer levels (150, 125, 100, 75, 50% of RDF of both the crops). Among different fertilizer levels tested, application of 150 per cent RDF of maize and pole bean supplied to both the component crops (244.50:225:150 N, P and...
Chickpea þ mustard is a prominent intercropping system in Indian sub continent. The majority of the farmers adopt this system under resource constraint conditions. The integrated applications of fertilizers with organic compost and biofertilizers are considered essential for the sustainability of a system. Looking to lack of information on this aspect, a study was undertaken on 'Typic Ustochrept' soils found commonly in the North Plain Zone of India. Results revealed that integrated nutrient application (INA) [50% recommended dose of fertilizer (RDF) þ FYM at 5 t ha 21 þ biofertilizers (Rhizobium þ PSB)] significantly enhanced average plant height, crop biomass, leaf area index, number and dry weight of root nodules of chickpea and plant height and crop biomass in mustard as compared to control. INA also produced significantly more grain and biological yield of chickpea and mustard and more chickpea equivalent yield (2664 kg ha 21 ) and net return (US $617 ha 21 ) as compared to control grown under intercropping system. INA also significantly increased the NPK content in shoot and grain of chickpea and mustard as compared to control causing significantly higher total uptake of nitrogen, phosphorus and potassium in chickpea and mustard. This treatment also made available more nitrogen, phosphorus and potassium in the soil after the harvest of crop in comparison to chickpea þ mustard intercropping system under moisture stress conditions.

Background: Intercropping maize with legumes can enhance diversity, stability, complementary sharing of resources, maintain soil fertility, productivity and livelihood of the farmers. The current study was aimed to develop the scientific knowledge of maize and pulse intercropping and their combinations in different planting structures. Methods: The field experiment consisted of seven treatments viz. sole maize, sole soybean, sole green gram and two intercropping ratios of soybean and green gram with maize at 1:1 and 1:2 row ratios and laid out in randomized block design in four replications during 2018-19 at Imphal. The intercropping, economic and competitive efficiency indices were calculated accordingly. Result: Intercropping of maize either with soybean or green gram in 1:2 ratio gave the best combination based on intercropping and economic efficiencies. Maize + soybean at 1:2 row produced the highest maize equivalent yield (82.65 q ha-1), system productivity (22.60 kg ha-1 day-1...
An experiment was conducted in farmers fields to investigate the effects of intercrops on the yield of mango cultivar 'Baneshan' with the aim to maximize the production potential and economic returns from mango-based intercropping systems in various villages of Nuzvid mandal, Krishna District, Andhra Pradesh. The treatments include, Mango + Horsegram, Mango + Bhendi, Mango + Beans, Mango + Brinjal, Mango + Tomato, Mango + Tobacco, Mango + Paddy and Mango + Maize. All the intercrops were sown / transplanted during rainy season only (Kharif). Cultivation of tomato as an intercrop in mango orchard recorded significantly highest mango yield (6222.20 kg/ha) followed by brinjal (5951.37 kg/ha) than the other intercropping systems. The lowest yield (3791.64 kg/ha) was recorded with maize as an intercrop. The highest monetary net return (Rs. 143138.90/ha) and BCR of 2.72 was obtained with brinjal intercroppping in mango orchard. Intercropping was effective in sustaining income and employment generation especially during the pre-production phase and "off" year especially for small and marginal farmers. Thus, intercropping in mango orchards can help farmers for year round production, employment, reduced cost of cultivation and increase monetary returns besides providing nutritional security.

Response of Cotton and Soybean Intercropping System to Integrated Nutrient Management
Aims: Field experiment was conducted to study the integrated nutrient management on yield, all yield components and resource use efficiency of cotton and soybean intercropping system. Study Design: Randomized complete block design with three replications and twenty treatments. Place and Duration of Study: Plot number '101' of 'D' block, All India Coordinated Research Project, Main Agricultural Research Station, University of Agricultural Sciences, Dharwad, Karnataka (India) during June 2016. Methodology: As per the treatments, organic manure (FYM) and green leaf manures (gliricidia and pongamia) were applied 15 days before sowing of the crop. Vermicompost was applied on the spot to soil before dibbling of seeds in cotton and soybean intercropping system in 1:2 row proportions, soybean introduced as intercrop in cotton with row spacing of cotton 120 cm and soybean 30 cm. Results: Results revealed that all the yield components like number of bolls per plant, boll weight, seed cotton yield and cotton stalk yield in cotton and number of pods per plant, seed weight per plant, seed yield and haulm yield were higher under sole crop. Application of 150 and 125% RDF for cotton and soybean intercropping system found higher yield and yield components of cotton and soybean. However, the land equivalent ratio (LER), area time equivalent ratio (ATER) and cotton equivalent yield (CEY) were higher in intercropping system than sole crops. Conclusion: Application of 125% RDF for both crops was found to be agronomically feasible, economically viable, environment friendly and in sustainable approach. In addition to this it provides insurance against inter-climatic changes.
