tailieunhanh - Rainwater management for sustaining groundnut productivity under dry farming conditions

A field experiment was conducted during kharif season of 2011-12 to 2016-17 to study the rain water management for sustaining groundnut productivity in medium black soils under dry farming condition at Main Dry Farming Research Station, Junagadh Agricultural University, Targhadia of Nourth Saurashtra Agro climatic Zone of Gujarat. The experiment consisting 2 main plots (2 levels of tillage) and 5 sub plot treatments (Management practices) laid out in split plot design with four replications. Significantly higher pod yield and haulm yield was obtained under the application of FYM @ 10 t/ha and kaolin @ 4 % (M1) spray and Ploughing every year up to 20 cm in set row (T1) as compared to control, while it were found non significant in combined effect of tillage and management practice. Maximum rain water use efficiency and crop water use efficiency was recorded in ploughing carried out every year up to 20 cm in set row (T1) practice and application of FYM @ 10 t/ha + Kaolin @ 4% spray (M1) under tillage and management practices, respectively. On the basis of pooled result ploughing carried out in alternate year up to 20 cm in set row under tillage practices gave the maximum net returns () with B: C ratio of . While in Management practices, application of FYM @ 10 t/ha and kaolin @ 4% spray (M1) gave the maximum net returns () with B: C ratio of as compared to rest of treatments. | Rainwater management for sustaining groundnut productivity under dry farming conditions
