Abstract:
Potato growing in north Gujarat is most prevalent practice since last so many years. It is important rabi crop and gives good amount of money per unit area with best management practice. Different fertilizers are applied by the farmers during potato growing in basal as well as top dressing. If fertilizers are to be given in drip system it will reduce the cost of application and increase fertilizer use efficiency of applied fertilizers. In the market different types of water soluble fertilizers are available now days, so to find out the best nitrogen source of fertilizers and to determine the optimum doses of said fertilizers in drip, this experiment is formulated. The experiment were undertaken during rabi 2019, 2020 and 2021 at Agricultural Research Station, S.D. Agricultural University, Aseda (Gujarat). The treatments comprised of three levels of source of nitrogen (S): S₁: Urea, S₂: 17-44 + micro nutrient grade III (1.0%), S₃: WSF 19-19-19 and three levels of nitrogen (N) N₁: 100% RDN, N₂: 75% RDN, N₃: 50% RDN.The experiment was laid out in a factorial randomized block design with three replications. Significantly higher tuber yield were recorded under the WSF 19-19-19 (38.99 t/ha) and 100% (RDN) treatment (36.92 t/ha). Interaction effect showed no significant result.
