Abstract
A field experiment was conducted during the year 2018-19 to optimize integrated nutrient recommendations through soil test crop response approach for forage oats (Avena sativa L.) grown in a Mollisol of Uttarakhand. The experiment was conducted as per the technical programme and methodology of All India Coordinated Research Project (AICRP) on Soil Test Crop Response Correlation (STCR). Response of forage oats to selected combinations of three levels of farmyard manure (0, 5 and 10 t FYM ha-1), four levels of nitrogen (0, 40, 80 and 120 kg N ha-1), four levels of phosphorus (0, 30, 60 and 90 kg P2O5 ha-1) and four levels of potassium (0, 20, 40 and 60 kg K2O ha-1) at different soil fertility levels was studied. It was found that to produce one quintal forage yield, forage oats required 0.27 kg of N, 0.03 kg of P2O5 and 0.32 kg of K2O with FYM. The per cent contributions of N, P2O5 and K2O were 71.4, 33.7 and 59.9 from soil and 73.0, 7.51 and 90.4 from FYM, 89.6, 50.8 and 302.7 from chemical fertilizers and 102.4, 52.9 and 351.5 from conjoint use of chemical fertilizers with FYM. Using these data, fertilizer prescription equations were developed for adjusting fertilizer dose in forage oats for different range of soil test values and desired yield targets.
在2018- 2019年进行了一项田间试验,通过土壤试验作物响应法优化在北阿坎德邦Mollisol种植的饲料燕麦(Avena sativa L.)的综合营养建议。该试验是根据全印度土壤试验作物响应相关性(STCR)协调研究项目(AICRP)的技术方案和方法进行的。研究了不同土壤肥力水平下饲用燕麦对3个水平农家肥(0、5、10 t FYM hm -1)、4个水平氮(0、40、80、120 kg N hm -1)、4个水平磷(0、30、60、90 kg P2O5 hm -1)和4个水平钾(0、20、40、60 kg K2O hm -1)组合的响应。结果表明,饲用燕麦在FYM条件下,N用量为0.27 kg, P2O5用量为0.03 kg, K2O用量为0.32 kg。土壤对N、P2O5和K2O的贡献率分别为71.4、33.7和59.9%,化肥对N、P2O5和K2O的贡献率分别为73.0、7.51和90.4,化肥对N、P2O5和K2O的贡献率分别为89.6、50.8和302.7,化肥与化肥联用对N、P2O5和K2O的贡献率分别为102.4、52.9和351.5。利用这些数据,建立了根据不同土壤试验值范围和期望产量目标调整饲草燕麦肥料用量的配方方程。
