Abstract
Abstract: The field experiment entitled “Impact of organic nutrient modules on productivity of pigeonpea based intercropping system’’ was conducted during Kharif season of 2018-19 at research farm of Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (Maharashtra) to find out effect of different organic integrated nutrient management on pigeonpea based intercropping systems. The experiment was laid out in Strip Plot Design (SrPD) with four main plot factors i.e. intercropping system (T1 – Sole Pigeonpea, T2 - Pigeonpea + Soybean 1:4, T3 - Pigeonpea + Foxtail millet 1:4 and T4 - Pigeonpea + Cotton 1:4) and three sub plot factors i.e. organic integrated nutrient management (N1 – 100% FYM + Vermicompost, N2 – 75% FYM + Vermicompost + 25% Neem cake and N3 – Control) replicated three times. The varieties adopted are PKV-Tara (pigeonpea), AMT-1001 (soybean), Co 1 (foxtail millet) and AKA-7 (cotton).
Plant height (cm) was higher in pigeonpea + cotton (1:4) intercropping system. Number of leaves plant-1 was not influenced by the intercropping system. Leaf area, leaf area index and number of branches was maximum at 120 DAS in pigeonpea + foxtail millet (1:4) intercropping system. Number of root nodules and root volume of the pigeonpea crop, dry matter accumulation plant-1 (g) and root dry matter accumulation plant-1 (g) was more in sole pigeonpea. Total leaf biomass added (kg ha-1) and total biomass added for in-situ decomposition (kg ha-1) was higher in pigeonpea + soybean (1:4) intercropping system than other intercropping system. Number of pod plant-1, number of seed plant-1, seed yield (kg ha-1), stalk yield (kg ha-1) and total uptake of NPK (kg ha-1) was found higher in pigeonpea + soybean (1:4) intercropping system. Among organic integrated nutrient management treatment 75% FYM + Vermicompost + 25% Neem cake significantly influenced dry matter accumulation in plant (g) at 90 and 120 DAS, root dry matter (g) at 90 DAS, number of pod plant-1, number of seed plant-1, grain yield (kg ha-1), stalk yield (kg ha-1) and NPK uptake.
Pigeonpea + Soybean (1:4) intercropping with organic integrated nutrient management of 75% FYM + Vermicompost + 25% Neem cake was found significantly higher seed yield (kg ha-1), pigeonpea equivalent yield (kg ha-1), system productivity (kg-1 ha-1 day-1), net monetary returns, B:C ratio and system profitability (Rs.-1 ha-1 day-1). Quality parameters viz. protein content (%), protein yield (kg ha-1), oil content (%), oil yield (kg ha-1) were also found higher values in pigeonpea + soybean (1:4) intercropping system.
In brief, OINM combination of 75% FYM + Vermicompost + 25% Neem cake in pigeonpea + soybean (1:4) intercropping treatment recorded higher PEY and economic returns.
Description
Description: The investigation studied the interaction of different organic integrated nutrient modules on different pigeonpea based intercropping systems for growth, yield attributes and yield of component crops and also impact on soil fertility improvement. The study has also tried to identify productive and profitable combination of intercropping system with organic integrated nutrient module.
