| dc.description.abstract | Field experiment was conducted during kharif 2009 at Agricultural College Farm, Karekere, Hassan on sandy loamy soil to study the effect of different sources and time of fertilizer application on uptake, growth and yield of potato under rainfed condition in Hassan District. The experiment was laid out in a randomized complete block design with four treatments replicated thrice. The potato tuber yield (16.50 t ha-1) with the application fertilizers as per the farmers practice (6 bags of 20:20:0:13 and 50 kg urea ha-1) and FYM @ 25 t ha-1 alone (10.92 t ha-1) was significantly lower than that obtained with application of RDF from different sources (N from urea or AS, P from SSP or DAP and K from MOP or SOP) and time of application (at planting or at 15 days after planting) along with FYM @ 25 t ha-1 (20.64 to 22.24 t ha-1). However, the highest tuber yield of 22.24 t ha-1 was obtained with the application of RDF through DAP, urea and SOP along with FYM @ 25 t ha-1 which was at par with the tuber yield recorded in other RDF treatments. The increase in yield due to application of RDF might be attributed to balanced supply of nutrients to the crop at appropriate time. The content and uptake of both macro and micronutrient in haulm and tuber increased with the application of RDF through different sources and their time of application as compared to that observed with farmers practice. The available nutrient status of both macro and micronutrients was increased in the soil after the harvest of the crop due to application of RDF from different fertilizer source along with FYM. Application of recommended dose of NPK from different fertilizer sources along with FYM resulted in higher gross returns and net returns compared to farmers practice. The highest benefit: cost ratio (2.55:1) was observed with the application of RDF through urea, SSP and MOP at planting when FYM cost was not included. | en_US |
