Double Purpose (Forage and Seed) of Mungbean Production 1-Effect of Plant Density and Forage Cutting Date on Forage and Seed Yields of Mungbean (Vigna radiata (L.) Wilczck)

Abstract

Abstract: Two field trials were implemented during summer of 2004 and 2005 seasons at private farm, Al Nagah village, South Al-Tahrir province, Al Behaira Governorate, Egypt. The aim of study was to quantify and qualify both forage and seed yields of local mungbean variety (Kawmy-1) under 3 plant densities low density (LD), medium (MD), high (HD) whichwere 25, 43, 62 plant/m 2 and 3 forage cutting date 45,55,65 days after sowing (DAS). Results indicated that due to plant density HD 62 plant/m 2 produced the highest forage fresh yield with highest dry matter% and harvest index-MD 43 plant/m 2 produced highest no. of pods/plant, seed yield/plant,/ha, bio-yield/ha-LD 25 plant/m 2 was the best in no. of branches/plant, seed index, protein% in forage and in seeds. Due to forage cutting date plants were cut 45 DAS produced highest no. of branches, pods/plant, seed index, seed yield/plant,/ha, bio-yield/ha, protein% in seeds. Latest cut date 65 DAS gave the highest forage fresh yield, dry matter%, protein% and harvest index. Interaction of 43 plant/m 2 X45 DAS came in the 1st order in branches/plant, protein% in seeds. HDx65 DAS was the best in forage fresh yield/ha, dry matter% and harvest index. LD x 65 DAS was the best in forage protein%
