Effect of Deficit Irrigations and Sowing Methods on Mung Bean Productivity

Abstract

A field experiment was designed to study the response of Mungbean to deficit irrigation levels and sowing methods. Randomized Complete Block Design (RCBD) with split plot arrangement replicated three times. Water treatments were controlled at I₀ (zero percent irrigation), I₃₃ (33% of full irrigation), I₆₇ (67% of full irrigation) and I₁₀₀ (full irrigation). Full irrigation was determined on the basis of 65% management allowed deficit (MAD). Results shows that I₆₇ and I₁₀₀ not significant for pods plant^-1 while these were highly significant for the sowing methods. The pods per plant are highly significant for I₀ and I₃₃ levels. The sowing methods and irrigation levels both have significant impact on grain yield and biological yield. The biological yields continuously and consistently increase with the increase in irrigation levels. The harvest index of Mungbean and its water productivity both increase in irrigation levels certain level. The maximum irrigation applied at 65% MAD substantially decreases the Mungbean water productivity when compared to the harvest index. It was concluded that Mungbean MAD in semi-arid region of Peshawar may be exploited further; more moisture contents may be further extracted before applying next irrigation in raised bed technique in special and as usual in flat beds.
