Abstract
Abstract: The present investigation entitled, “Effect of phosphogypsum on nutrient uptake, yield and quality of summer groundnut” was undertaken during the summer 2019-20 at Oilseeds Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. The experiment was laid out in Randomized Block Design with nine treatments in three replications. The objectives were to study the effect of phosphogypsum on nutrient uptake, yield, quality and soil properties of summer groundnut. The treatments comprised of control, RDF alone and their combinations with phosphogypsum and gypsum. The soil of the experimental site was moderately alkaline in nature. The fertility status in the soil indicated that the soil was very low in nitrogen, low in phosphorus, sulphur and deficient in zinc and boron content.
The significantly highest in pod yield (20.87 q ha-1) and haulm yield (25.80q ha-1) of summer groundnut was recorded due to soil application of RDF along with phosphogypsum @ 400 kg ha-1 followed by soil application of RDF along with gypsum @ 400 kg ha-1. The content and uptake of N, P, K, S, Ca, Mg, Zn, Fe, Mn, Cu and B improved in pod and haulm of groundnut significantly due to the soil application of RDF along with 400 kg phosphogypsum ha-1 followed by soil application of 400 kg gypsum ha-1 along with RDF. The improvement in fertility status of soil for major nutrients and for micronutrients at harvest stage was greatly influenced due to the soil application of RDF along with phosphogypsum @ 400 kg ha-1 followed by soil application of gypsum @ 400 kg ha-1 along with RDF.
The quality parameters i.e. 100 kernel weight, oil and protein content were also improved due to soil application of 400 kg phosphogypsum ha-1 along with RDF followed by soil application of gypsum @ 400 kg ha-1 along with RDF.
Considering the yield, quality and fertility status of soil for growing groundnut on Vertisols it is suggested to use the cheapest multinutrient source i.e. phosphogypsum and gypsum along with RDF.
