Rice Cultivation and Yield Improvement

High and unpredictable rainfall during the rainy season in Igatpuri leads to rice (Oryza sativa) as the popular crop in the region. The current cultivation practices by small farmers are causing nutrient depletion and fertilizer losses due to inefficient fertilizer application practices. There is urgent need to improve farmers skills through effective transfer of technology, judicious use of inputs, and thereby reversing declining productivity trends. Several reports studies indicated that deep point placement of urea super granules (USG) or pilow shaped USG so called briquettes is more efficient than conventionally applied nutrients, (Westsellar, 1985; Katyal et al., 1985; De Datta and Buresh, 1989; Savant and Stangel, 1995; Awasthe and Mishra, 1987 and More and Shinde, 2002). Efficient management of fertilizer through briquettes containing nitrogen and phosphorus further enhanced the efficiency of fertilizers in lowland transplanted rice (Bulbule et al., 2003). Potassium has a key role in rice for resistance development against pest and diseases, for better stand under adverse climatic condition and to improve quality parameters in rice crop. Hence, present investigation was undertaken to study the efficient use of NP briquette with different levels of potassium on lowland rice.
