International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad Combinations of 12 treatments were replicated thrice resulting in total of 36 experimental plots. In the case of the flat planting method, spacing between the rows and plant-to-plant was kept at 60 cm and 20 cm, respectively. A similar procedure was followed in the conservation furrow method except that after planting 4 rows, every 5 th -row plantation was skipped and plant-to-plant spacing was kept at 18 cm. In ridge planting, seeds were placed 6-7 cm above the base on the side of ridges spaced 60 cm apart with a 20 cm distance between the plants. In the bed planting method, one row of maize was sown on top in the center of raised beds 67.5 cm wide having a top flat of 37.5 cm and a furrow 30 cm with plant-to-plant spacing of 18 cm. The crop was harvested last week of September 2020. Results Among planting methods, bed planting method produced a maximum grain yield of 33.8 qha -1 (Table 1). Bed planting gave a 20.7 percent higher yield followed by ridge sowing which produced a 12.7 percent higher grain yield at Ballowal Saunkhri as compared to flat sowing. Higher grain yield (33.5 qha -1 ) was obtained under earthing up and it was statistically better than under straw mulch and no interculture. Earthing up significantly increased the grain yield by 27.5 percent over no interculture and 7.2 percent over straw mulch treatment. The highest stover yield was observed under bed sowing (72.6 q ha -1 ) which was significantly higher over the flat sowing (60.9 q ha -1 ) method. The bed planting method resulted in a maximum net return (31657 Rs) and B: C ratio (1.84) per hectare than other planting methods. Among moisture conservation practices, earthing up produced the highest net returns (30865 Rs) and B: C ratio (1.79). The higher net returns of 10475 Rs per hectare were obtained with earthing up moisture conservation practices as compared to no interculture.

T4a-30P-1578 Escaping Moisture Stress in Steep Slopes by Altering the Time of Planting (Early Sowing) in Garden Pea N. Ajitkumar Singh*, Solei Luiram, K. Vikramjeet, N. Sureshchandra Singh, Yirmila.V. Zimik and P.A. Ramsem Krishi Vigyan Kendra Ukhrul, ICAR Research Complex for NEH Region, Manipur Centre *ajitsinghkvk@gmail.com, vkukhrul@gmail.com Garden pea (Pisum sativum L.) is one of the leading horticultural crops of Ukhrul district Manipur and is generally grown in October-November. Planting sites are generally located on steep hill slopes with an altitude ranging from 1,300 to 1,800 m above mean sea level. The major growers within the district are under the Sub division of Ukhrul and Chingai block. In recent years there has been a rapid decline in the production and productivity in this district including the adopted NICRA villages due to terminal drought and frost. Being, not economically feasible to go for irrigation throughout the season in such terrine, this investigation “altering the planting time” (early sown) was taken up. For this intervention, the NICRA village Ramva and Lungshang were selected, after analysing the rainfall pattern since 2013 and started demonstration from the year 2018. Soil samples were collected for moisture and other chemical analysis from demonstrating plots and farmers’ fields. The data reveal that moisture content was significantly high (30.2-36.5%) in the early sown demonstrated plot (August) as compared to farmers’ field (19.3-25.4%) late sown (October). Economically early sown gives the maximum yield of 28.3-30.8 q/ha as compared to late sawn (18.4-21.6 q/ha), and return per rupee investment is 3.2 and 1.8 respectively. From this study, it can be concluded that moisture stress 630 | Page Resource conservation and rainfed agriculture
