Studies Of Rain Water Management Under Blackgram Indian Mustard Cropping System In Jhararghat Hillocks Watershed Of Lalitpur District

Abstract

An experiment was conducted during two consecutive year of newline2015-2016 and 2016-2017 at Hillocks and Valley Watershed of newlineJhararghat, Lalitpur, situated in catchments area of river Betawa. newlineThe soil of watershed area was sandy loam locally known as Rakar, newlinehaving pH 8.1, organic carbon 0.26%, total nitrogen 0.02%, available newlinephosphorus 10.38 kg/ha and available potassium 227.00 kg/ha newlineinitially before starting of present experiment. The trial was newlineconducted on farmers fields under blackgram-Indian mustard newlinecropping system. There were four treatments comprised of newlineconventional system, runoff recharge in stony dug wells, runoff newlineharvesting at hill bottom in natural water impounding structure and newlinerunoff collection in constructed water storage structure. The newlinetreatments were evaluated on the basis of growth, yield attributes and newlineyield in blackgram and Indian mustard. The blakgram variety Azad newlineUrd-3 and Indian mustard CV. Varuna were sown with conservation newlineagronomical practices. newlineThe highest grain yield of blackgram by 9.06 q/ha was reaped newlinefrom runoff collection in constructed water storage structure of pilot newlinearea. The sowing of Indian mustard after blackgram in the same newlinetreatment (T4 ) gave highest grain yield by 24.87 q/ha. newlineThe growth and yield traits of both crops were concordant to the newlineyields. The sowing of blackgram and Indian mustard under black newlinegram Indian mustard cropping system in the treatment of runoff newlinecollection in constructed water storage structure (T4) system of rain newlinewater management gave maximum net return by Rs 1,20,675/ha and newlinebenefit cost ratio 1:3.20. The water use efficiency and production newlineefficiency value were also recorded higher in T4 treatment. newline newline
