Abstract

Foliar application can be used along with the soil application of fertilizers to enhance the yield and quality of crops for a sustainable approach to nutrient management. In this context, a field experiment was conducted with green gram (cv: NVL-516) in anacidic soil of the Agricultural Research Farm, Siksha ‘O’ Anusandhan, Bhubaneswar with the objective to study the impact of combined soil and foliar application of nutrients on yield and protein content of summer green gram in Odisha. The experiment was laid out in a Randomized Block Design with three replications and eight treatments consisting of recommended dose of Nitrogen, Phosphorous, Potassium and Sulphur (NPKS) along with foliar application of 2% urea, diammonium phosphate (DAP), KCl, N: P: K (19:19:19) and 1%KNO3 and control.Foliar application was done two times at 30 and 45 DAS. The highest yield (1582 kg ha-1 ) was recorded in treatment where 1%KNO3 was applied as foliar spray along with the recommended dose of NPKS and was at par with 2%DAP(1574 kg ha-1). The protein content of seeds was found highest in treatment with foliar application of urea (22.6%) followed by KNO3 (22.4%), N: P: K (19:19:19) (22.4%) and DAP(22.1%). The protein content strongly correlated with the N concentration of seeds.

夏季绿克对土壤和叶面复合施用主要必需养分的响应

叶面施用可与土壤施用一起使用，以提高作物的产量和质量，从而实现可持续的养分管理方法。为此，在布巴内斯瓦尔省Siksha ' O ' Anusandhan农业研究农场的酸性土壤中进行了绿克(cv: NVL-516)的田间试验，目的是研究土壤和叶面配施养分对奥里萨邦夏季绿克产量和蛋白质含量的影响。试验采用随机区组设计，设3个重复，8个处理，分别为氮磷钾硫(NPKS)推荐剂量，叶面施用2%尿素、磷酸铵(DAP)、氯化钾、N: P: K(19:19:19)和1%KNO3及对照。叶面施用于30和45 DAS进行两次。在叶面喷施1%KNO3和推荐剂量NPKS的处理中，产量最高(1582 kg ha-1)，与2%DAP(1574 kg ha-1)相当。籽粒蛋白质含量以叶面施尿素最高(22.6%)，其次为KNO3(22.4%)、N: P: K(19:19:19)(22.4%)和DAP(22.1%)。蛋白质含量与籽粒氮浓度呈极显著相关。
