Effect of Ghanajeevamruth and Amirthakaraisal on growth and yield of Greengram (Vigna radiata L.)

Abstract

In India, Greengram (Vigna radiata L.), often known as Mungbean, is a significant pulse crop that is primarily planted during the Zaid and Kharif seasons. It is a member of the Fabaceae family. Organic farming is regarded as one of the finest ways to lessen the excessive use of chemical fertilizers that pollute the environment. During Zaid season 2024, a field experiment was carried out at SHUATS Model Organic Farm, Department of Agronomy, SHUATS, Prayagraj (U.P.) "to study the effects of Ghanajeevamruth and Amrithakaraisal on growth and yield of Greengram." Nine treatments were used in the randomized block design experiment, which was duplicated three times. Ghanajeevamruth (100%, 75%, and 50%) and Amirthakaraisal (100%, 75%, and 50%) liquid organic manures were used in varying amounts as part of the treatment. The experimental field soil was sandy loam in texture, moderately basic in reaction (pH 7.1), available medium organic Carbon (0.742 %) low in available nitrogen (245.5 kg/ha), and very high accessible phosphorus (32.3 kg/ha) and available potassium (248.7 kg/ha). The result showed that significantly higher growth parameters viz., plant height (53.37cm), number of nodules (11.27/plant),number of branches(11.60/plant),dry weight (8.45g/plant) and yield attributes such as effective pod/plant (10.23), seed/pod (11.10), test weight (39.00 g), seed yield (1476.44 kg/ha) and stover yield (2273.70kg/ha) were observed with application Ghanajeevamruth 100% and foliar spray of Amirthakaraisal 100%(T1). Highest gross return (Rs.1,122,662.87/ha), net return (Rs.85062.87/ha) and benefit cost ratio (2.26) was also recorded in the same treatment. This concludes that application of Ghanajeevamruth 100% along with foliar spray of Amirthakaraisal 100% performed better in growth and yield of Greengram has recorded highest test weight, grain yield, stover yield, net return and benefit cost ratio and as well as it is economically profitable.
