A Field experiment was conducted during rainy seasons of 2015-16and 2016-17 to study the response of kharif pigeonpea (Cajanus cajan) to different levels of NPK fertilization under rainfed in black soil. Pooled data shows that application of phosphorus with 50 and 75 kg/ha and nitrogen with 20 and 40 kg/ha gave significantly higher grain and stalk yield and harvesting index of pigeonpea. Maximum grain yield (1829 kg/ha) was realised with application of 40-75-20kgNPK/ha it was at par with application of 20-50-0kgNPK/ha (1755 kg/ha).Absolute control resulted in 1283kg/ha. This treatment also gave the higher total plant uptake of N P K by pigeonpea. The study recommended that soil application as basal Phosphorus 75 kg/ha increased 4-5percent grain yield of pigeonpe over a existing recommendation Phosphorus50kg/ha, and pigeonpea crop fertilizer with 20-50-0kg NPK/ha was most productive and profitable.

A research experiment was conducted on cotton during kharif 2015 and 2016 at Regional Agricultural Research Station (RARS), Warangal (Telangana) "To study the Influence of methods and stage of application of zinc, magnesium and boron on yield attributes, yield and micronutrients uptake of cotton in rainfed alfisols". Pooled results indicated that, foliar application of ZnSO4 @ 0.2% at 30 days, ZnSO4 + Borax @ 0.2% each at 45 days, Borax @ 0.2% + MgSO4 @ 1% at 60 days and MgSO4 @ 1% at 75 days after sowing along with soil application of recommended dose of fertilisers (RDF) recorded significantly higher sympodial branches, number of bolls per plant, seed cotton yield i.
