Impact of foliar nutrition on the yield and economics of greengram (Vigna radiata)

Abstract

The experiment was conducted at Anbil Dharma lingam Agricultural College and Research Institute, Trichy during summer season of 2018-19 to study the effect of foliar nutrition on the productivity of green gram. The experiment was laid out in Randomized Block Design and replicated thrice with eight treatments comprising of T1- Control + T2- Foliar spray of DAP 2% + T3- Foliar spray of KCl 2% + T4- Foliar spray of Pulse wonder @ 2 kg ac-1 + T5- Foliar spray of Panchakavya 5% + T6- Foliar spray of Cow urine 5% + T7- Foliar spray of Vermiwash 5% + T8 – Foliar spray of PPFM 2%. The yield attributes and yield were recorded and worked out the economic analysis using BCR. The results revealed that the foliar application of TNAU Pulse wonder @ 2 kg ac-1 significantly recorded the highest yield attributes viz., no. of pods/plant, no. of seeds/pod, test weight and grain yield of 839 kg ha-1 Which is on par with Panchakavya 5% which registered 834 kg ha-1. From the above results, it has been concluded that TNAU Pulse wonder @ 2 kg ac-1 to enhance the productivity in green gram with the B: C ratio of 2.34.
