Abstract
A field experiment was conducted during kharif season of 2020 at research field of AICRP for Dryland Agriculture, Dr. Panjabrao Deshmukh Krishi Vid¬¬¬¬yapeeth, Akola, (Maharashtra) to study the effect of organic sources of nutrients on soil fertility and yield of rainfed cotton(Gossypiumspp.) in Vertisols. The experiment was laid out in randomized block design with three replications and nine treatments. The results revealed that, there was a reduction in bulk density, pH and electrical conductivity and an increase in hydraulic conductivity and organic carbon content with application of 50% N through FYM + 50% N through gliricidia green leaves. This treatment also resulted in significantly higher available N (193.2 kg ha-1) and K (331.1 kg ha-1) content whereas available P (15.98 kg ha-1) content was higher with application of 50% N through FYM + 50% N through vermicompost. Improvement in the seed and stalk yield of cotton was observed with application of 50% N through FYM + 50% N through gliricidia green leaves. Seed and stalk yield was increased by 8.9% and 7.7% with application of 50% N through FYM + 50% N through gliricidia green leaves as compared to inorganic treatment, respectively. The minimum seed (540.9 kg ha-1) and stalk (997.2 kg ha-1) yield were recorded with application of 12 t FYM ha-1.
2020年农作季,在AICRP旱地农业研究领域,Panjabrao Deshmukh Krishi Vid -¬¬¬yapeeth博士,Akola (Maharashtra)进行了一项田间试验,研究有机养分来源对土壤肥力和Vertisols雨养棉花(Gossypiumspp.)产量的影响。试验采用随机区组设计,3个重复,9个处理。结果表明,施用50%氮肥+ 50%氮肥可降低叶片的容重、pH和电导率,提高叶片的导电性和有机碳含量。施用50%氮肥+ 50%蚯蚓堆肥可显著提高速效氮(193.2 kg ha-1)和速效钾(331.1 kg ha-1)含量,而速效磷(15.98 kg ha-1)含量显著高于施用50%氮肥。通过FYM施用50%氮肥+叶片施用50%氮肥,棉花籽粒和茎部产量均有提高。与无机处理相比,通过FYM施用50%氮肥+通过叶片施用50%氮肥,种子和茎部产量分别提高8.9%和7.7%。施用12 t FYM hm -1时,种子(540.9 kg hm -1)和茎(997.2 kg hm -1)产量最低。
