MOISTURE STRESS EFFECT ON PIGEON PEA (Cajanus cajan L.) YIELD AND GROWTH ATTRIBUTING CHARACTERS
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 47
Abstract
A field experiment was conducted to examine the effect of moisture stress on growth and yield of pigeon pea under deep black soil during the khariff season of 2013 and 2014. Results indicated that moisture stress imposed at flowering stage was recorded detrimental for growth and yield and the treatment T3 and T1 (control) imposed at flowering stage increased moisture content by 8.50 and 37.91 % over moisture stress at 50 % flowering stage, but the treatment T3 was at par with the treatment T1 in all the stages. The increased pod yield was recorded 2.24 % over the control at grain development stage. Treatment T3 and T1 imposed at flowering stage increased plant height (8.90 % and 8.65 %) and number of branches (5.00 % and 15.00 %) respectively, over 50 % flowering stage. Significantly treatment T1 had lower values for growth and yield parameters due to different reasons viz., moisture stress, pest attack, temperature effect the 70 % pods were damaged. The higher number of pods (6570 nos. ha-1) was recorded in Treatment T3 and exhibited its superiority over rest of the treatments. This indicated that among different growth stages, the flowering stage is most critical for irrigation in the pigeon pea crop.
