Abstract

Intensive land use in the long term can cause land degradation, affecting soil fertility, especially on Vertic Endoaquepts in Pati that have been managed as rainfed rice fields. The characteristics of rainfed rice fields are low nutrient availability and rice yields. This study aimed to determine the effect of tillage depth management and soil ameliorants on nutrient availability, plant uptake, and rice yield in rainfed rice fields. The field experiment that was conducted at farmer’s field used a split-plot design. The main plot was the treatment of tillage depth treatments (OT), with depths of 10 cm (T1) and 20 cm (T2). The subplots were ameliorant treatments (A), consisting of A1 = sugarcane leaf compost, A2 = rice straw compost, A3 = chicken manure, and A4 = cow manure, with each dose of 5 t ha-1. The Inpari 32 rice variety was grown for 95 days. Available N, P and K of the soil were measured at 0, 62, and 94 days after transplanting (DAT). Plant N, P, and K contents, plant height, number of tillers, and rice yield were measured at 62 DAT. The results showed that the interaction of soil depth and ameliorant significantly affected soil available P and K but had no significant effect on soil available N. Ameliorant treatment of cow manure significantly increased rice yield.

Abstract

Cowpea (Vigna unguiculata L. Walp), a botanical protein source, exhibits resilience in the face of drought-induced stress on rainfed rice fields, especially in dry season crop patterns. Cowpea growth depends on the availability of nutrients in the soil, including potassium (K). In fact, low K availability (exchangeable K is ≤ 0.04 cmol(+) kg-1) is one of the obstacles in rainfed rice fields, especially in increasing crop yields, including cowpea. Therefore, K supplies from various sources are needed to improve soil and cowpea productivity, such as K fertilizer and manure. This study was carried out to determine the response of nutrient management to increase cowpeas’ yield and exchangeable potassium on rainfed rice fields. The field experiment used a randomized block design, with six replications and six fertilizer management treatments, specifically to control composted cattle manure (CCM), Nitrogen Phosphate Fertilizer (NP), CCM+NP, NPK Fertilizer, and CCM+NPK. The parameters observed include plant height, yield components, seed yield, and exchangeable K. Fertilizer management affects the cowpea yield, yield components, K-Uptake, and exchangeable potassium, with the best treatment depicted as CCM+NPK treatment. Compared to the control, CCM by itself and in combination with inorganic fertilizer increases the kernel yield of cowpea by as much as 54-104%, K uptake as much as 40.9-68.2 kg K/ha, and exchangeable K in soil ranging from 37.8-101.3%. It is indicated that the CCM could supply nutrients, including potassium, to overcome potassium deficiency in rainfed rice fields. Furthermore, applying CCM and cultivating cowpeas in rainfed rice fields during the dry season, with water as a limiting factor, is an appropriate option to enlarge the plant yield.
