Kurzfassung:
The hot and semi-arid region is prone to meteorological droughts; the lack of rain is frequently accompanied by hot temperatures, strong winds, and low humidity, which has the impact of limiting nutrient uptake and agricultural yields. To overcome this problem a field study conducted during June, 2020 kharif season at farmers field, Chinna Dudyala village, Muddanur, Kadapa district, Andhra Pradesh aimed to determine the effect of organic mulches and foliar spray of kaolin on NPK uptake in enhancing yield and economics of dry land maize (Zea mays). One of the most important techniques for preserving soil moisture was mulching, which also reduces evapotranspiration when anti-transpirants are used. The experiment comprised nine treatments (T1 to T9) with four types of organic mulches viz., Paddy straw, Ground-nut haulm, Coir-pith, and Sugarcane trash, with foliar spray of kaolin intervals on 40 DAS, 20 & 40 DAS and farmers practice to minimize water stress and improve the nutrient uptake by plant. Among the application of the treatments, coir-pith mulch + foliar spray of kaolin @ 3.0% (T6) on 20 DAS & 40 DAS had significant effect on NPK uptake with N (187.15 kg ha-1), P (69.60 kg ha-1) and K (156.22 kg ha-1) and enhanced grain yield (6976 kg ha-1) and stover yield (10980 kg ha-1), highest gross returns (138034 ₹. ha-1) and BCR (2.63) and was superior to all the other treatments. The present study would help to effectively utilise the available resources, enhance growth and productivity in maize crop and to make economically viable to the farmers of semi-arid regions.
