“…The cowpea residue is typically incorporated into the soil and therefore the higher N and P content in the shoots resulting from enhanced plant growth and nitrogen fixation could provide additional residual N and P for subsequent crops (Giller, 2002). In agreement with other studies (Dekhane et al, 2011; Musa et al, 2011), inoculation and P fertilization increased crude protein content of cowpea grain which is a major advantage in terms of quality nutrition. Since cowpea is an important protein source for smallholder farmers, increase in the grain protein content would improve the quality of their diet.…”

Cowpea (Vigna unguiculata) is a major source of dietary protein and essential component of the cropping systems in semi-arid regions of Sub-Saharan Africa. However, yields are very low due to lack of improved cultivars, poor management practices, and limited inputs use. The objectives of this study were to assess the effects of rhizobia inoculant and P on nodulation, N accumulation and yield of two cowpea cultivars in Mozambique. Field study was conducted in three contrasting environments during the 2013/2014 and 2014/2015 seasons using randomized complete block design with four replications and four treatments. Treatments consisted of seed inoculation, application of 40 kg P2O5 ha-1, inoculation + P, and a non-inoculated control. The most probable number (MPN) technique was used to estimate the indigenous bradyrhizobia populations at the experimental sites. The rhizobia numbers at the sites varied from 5.27 × 102 to 1.07 × 103 cells g-1 soil. Inoculation increased nodule number by 34–76% and doubled nodule dry weight (78 to 160 mg plant-1). P application improved nodulation and interacted positively with the inoculant. Inoculation, P, and inoculant + P increased shoot dry weight, and shoot and grain N content across locations but increases in number of pods plant-1, seeds pod-1, and 100-seed weight were not consistent among treatments across locations. Shoot N content was consistently high for the inoculated plants and also for the inoculated + P fertilized plants, whereas the non-inoculated control plants had the lowest tissue N content. P uptake in shoot ranged from 1.72 to 3.77 g kg-1 and was higher for plants that received P fertilizer alone. Inoculation and P either alone or in combination consistently increased cowpea grain yield across locations with yields ranging from 1097 kg ha-1 for the non-inoculated control to 1674 kg ha-1 for the inoculant + P treatment. Grain protein concentration followed a similar trend as grain yield and ranged from 223 to 252 g kg-1 but a negative correlation between grain yield and protein concentration was observed. Inoculation increased net returns by $104–163 ha-1 over that for the control. The results demonstrate the potential of improving cowpea grain yield, quality and profitability using inoculant, although the cost-benefit for using P at the current fertilizer price is not attractive except when applied together with inoculant at low P site.

“…Increases in the N content in seed apparently due to greater bioavailability of nitrogen from the applied integrated nutrient sources and subsequent efficient absorption of N by plant root. The findings are corresponding with the published results [9,10].…”

“…Correspondingly, their uptake into the straw also found statistically higher (153.91 and 23.41 kg/ha, respectively) with treatment T 6 . Application of organic and inorganic fertilizer together with biofertilizer facilitates the bioavailability of N and P, and thereby greater content and uptake of N and P into the straw [9,10,11]. cfu/g was observed with treatment T 10 , statistically followed by treatment T 6 .…”

Aim: To study the effect of integrated nutrient management (INM) on growth, yield and quality of dual purpose fodder oat. Study Design: Randomized Block Design. Place and Duration of Study: Anand Agricultural University, Anand during Rabi 2019-2021. Methodology: The experiment was laid out in randomized block design with four replications. The experimental treatments were consisted of ten INM treatments viz., T1 (100% recommendation dose of fertilizer; RDF’ 80-40-00 kg NPK/ha), T2 (10 t FYM/ha + 100% RDF), T3 (castor cake/ha + 100% RDF), T4 (poultry manure/ha + 100% RDF), T5 (neem cake/ha + 100% RDF), T6 (5 t FYM + 25% RDN from FYM + 75% RDF + biofertilizer), T7 (5 t FYM + 25% RDN from castor cake + 75% RDF + biofertilizer), T8 (5 t FYM + 25% RDN from poultry manure + 75% RDF + biofertilizer), T9 (5 t FYM + 25% RDN from neem cake + 75% RDF + biofertilizer) and T10 (50% RDN from FYM + 50% RDN from castor cake + biofertilizer). Amount of castor cake, poultry manure and neem cake were applied based on 10 t FYM/ha equivalent N, i.e., respectively 1.45, 3.23 and 3.27 t/ha. Results: The results revealed that quality parameters of fodder oat such as dry matter, dry matter yield, crude protein, ADF, NDF, crude fiber contents as well as ash content of green fodder and straw were found significant superior with application of T6 and T10 treatments. Similarly, NPK content and their uptake into the seed and straw were also found significantly higher with the same treatments. The physicochemical and biological properties of experimental field soil at harvest of oat crop were also considerably improved due to application of INM treatment as compared to initial soil nutrient status.

“…Thus, increased availability of nitrogen and phosphorus might have resulted in greater uptake by plant for proper development and ultimately increased their content and uptake in seed and straw. Similar results were also observed by Patel et al (2016b) [11] , Khan et al (2017) [3] . Venkatarao et al (2018) [17] and Pargi et al (2018) [9] .…”

A field experiment was carried out at College Farm, Navsari Agricultural University, Navsari on clayey soils during rabi season of 2017-18 to study the influence of inorganic fertilizer, organic manure and biofertilizers on nutrient content and uptake of Indian Bean (Dolichos lablab L.). Recommended dose of fertilizer recorded significantly the highest content and uptake of N and P. Application of biocompost @ 2.5 t/ha recorded significantly the highest nutrient content and uptake of rabi Indian Bean. Similar trend also recorded in case of available nutrient in soil after harvest. Most of the nutrient content, uptake and available nutrient in soil after harvest of Indian bean recorded significantly the highest under seed inoculation with Rhizobium + PSB over no seed inoculation.
