Abstract

Sustainable low-cost farming in (groundnut based) cropping system offers a much-needed alternative to conventional input-intensive agriculture. Keeping this in view a field experiment was conducted during rainy (kharif) season of 2022–23 at ICAR-Directorate of Groundnut Research, Junagadh, Gujarat on groundnut (Arachis hypogaea L.) to evaluate the performance of low-input agriculture with ZBNF (Zero-budget natural farming) vis-avis others. Experiment was conducted in a split plot design having 3 different farming practices, viz. Natural farming (NF); Integrated crop management (ICM or conventional farming); and Organic farming (OF) practices in main plot using 2 cultivars ‘GJG-22’ (Virginia Bunch) and ‘TG 37A’ (Spanish Bunch) in large sub plot (~1/100th of a hectare), replicated 8-times. Further, these permanent plots of 3 farming practices were cultivated with wheat (Triticum aestivum L.) (two cultivars, viz. ‘GW 451’ and ‘Lok 1’) in rotation during winter (rabi) season of 2022–23 following a residual exhaustive fodder crop of pearl millet [Pennisetum glaucum (L.) R.Br.] grown during spring/summer 2021– 22 prior to the experimentation. The study revealed that pod yield to the tune of 1,316–1,630 kg/ha was realized with low cost NF (or ZBNF) practice (higher yields with Spanish Bunch) vis-a-vis 1,448–1,779 kg/ha in OF practice. On the contrary, higher pod yield of 1,679–1,965 kg/ha was realized with the ICM practice employing improved production technologies. The growth/developmental parameters/values including economics and total system productivity were also higher under ICM practice. Furthermore, higher values in respect of all the groundnut plant attributes including economics and nutrient (NPK) uptake, and its efficiency (NPK uptake/100-kg pod) were evident under ICM practice. Similar crop responses were conspicuous in case of the succeeding wheat crop. Thus, overall crop response to farming practices were in the order: ICM>OF>NF; and the ratio of N, P, and K uptake for realization of higher per unit productivity (across farming practices and varieties) was observed to be 6.8:1.0:2.2 for groundnut and 3.9:1.0:3.3 for wheat. Thus, ICM practice comprising of judicious use of chemical fertilizers, manure and pesticides use was advantageous for realizing higher yield and return in groundnut-wheat. Further efforts are made to realize higher productivity of ecofriendly farming practices (ZBNF and OF).
