Abstract

The present field study was carried out during 2017–18 and 2018–19 rainy (kharif) and winter (rabi) seasons in order to examine the impact caused by integrated nutrient management (INM) on the yield and quality of the short grain aromatic rice (Oryza sativa L.)-greengram (Vigna radiata L.) combination. Two years experimental data concluded that integration of 50% recommended dose (RD) as fertilizer + 50% RD of nitrogen via farm yield manure (FYM) resulted in considerably higher economic yield (3837.1 and 3917.7 kg/ha) of short grain aromatic rice cv. Nua Acharamati which were at par with 75% RD as fertilizer + green manuring of dhaincha (3438.5 and 3539.1 kg/ha). Pooled data revealed that, residual effect of 50% RD as fertilizer + 50% RD of nitrogen (FYM) and 75% RD as fertilizer + Rhizobium + PSB in greengram recorded the highest number of pods/plant (18.2), seeds/pod (11.3), pod length (9.3 cm), test weight (32.7 g), seed yield (925.7 kg/ha) and stover yield (2240.7 kg/ha) in greengram cv. IPM-02-03. Application of 50% RD as fertilizer + 50% RD of nitrogen (FYM) to aromatic rice recorded the highest hulling recovery (75.8 and 75.5%), milling recovery (68.0 and 68.3%), head rice recovery (60.0, 59.7%) and crude protein content (8.75 and 9.11%) during both of the years experiment being at par with application of 75% RD as fertilizer + green manuring. Economics of the system revealed the highest gross return, net return and B:C ratio by application of 50% RD as chemical fertilizer + 50% RD of nitrogen (FYM) in rice followed by 75% RD as chemical fertilizer + Rhizobium + PSB in greengram.

综合营养管理模块,提高短粒香稻(Oryza sativa)-绿米(Vigna radiata)序列的生产力和经济性
为了研究综合营养管理(INM)对短粒香稻(Oryza sativa L.)-绿米(Vigna radiata L.)组合产量和品质的影响,本研究在2017-18和2018-19雨季和冬季进行。2年试验数据表明,50%推荐用量(RD) + 50%推荐用量(FYM)施用氮肥可显著提高短粒香稻的经济产量(3837.1和3917.7 kg/ha)。Nua Acharamati相当于75% RD作为肥料+绿肥(3438.5和3539.1公斤/公顷)。综上所述,50% RD作肥+ 50% RD施氮(FYM)和75% RD作肥+根瘤菌+ PSB的残留效应在绿克cv中获得最高的荚果数(18.2个)、种子/荚果数(11.3个)、荚果长(9.3 cm)、试重(32.7 g)、种子产量(925.7 kg/ha)和秸秆产量(2240.7 kg/ha)。IPM-02-03。与75% RD肥+绿肥处理相比,50% RD肥+ 50% RD氮(FYM)处理的芳香水稻脱壳回收率最高(75.8和75.5%),碾磨回收率最高(68.0和68.3%),抽穗回收率最高(60.0、59.7%),粗蛋白质含量最高(8.75%和9.11%)。从经济效益上看,施用50% RD作化肥+ 50% RD作氮肥(FYM)的总收益、净收益和B:C比最高,其次是75% RD作化肥+根瘤菌+绿图中的PSB。
