Effect of phosphorus, sulphur and biofertilizer on productivity and soil fertility after harvest of moongbean grown on light textured soil of Kachchh

Abstract

A field experiment consisted of 24 treatment combinations of three levels of phosphorus(0, 20, 40 kg ha-1) and three levels of sulphur (0, 20, 40 kg ha-1) and two level of biofertilizer in form of Rhizobium inoculation (inoculated and uninoculated) was conducted with four consecutive years from 2007-08 to 2010-11 were tested with three replications effect of under factorial Randomized Block Design at Bhachau-Kachchh to study the effect of P, S and Rhizobium on productivity and fertility of soil after harvest of moongbean. The soil of the experiment field was sand loamy with alkaline in reaction, low in nitrogen, sulphur and zinc, medium in phosphorus and potassium. Application of 40 kg P ha-1 and 40 kg S ha-1 along with Rhizobium inoculation significantly increased the productivity of moongbean and improved the nutrient availability of soil at harvest of crop over the control. Maximum economic benefits of gross realization, net realization along with highest BCR of 6.73:1 under the treatment combination P 2 S 2 R 1 .

Effect of Spacing and Levels of Phosphorus on the Growth and Yield of Green Gram (Vigna radiata) under Rainfed Condition of Nagaland

“…The increased in the parameters at 40 kg P 2 O 5 ha -1 might have been on account of stimulation of root growth of the crop as phosphorus plays an important role in various physiological process including root development, nodulation and N-fixation, better utilization of available growth resources viz., nutrient, moisture and solar radiation to a greater extent and accumulation of photosynthates. Similar results were also observed by Kadam and Khanvikar (2015), Sathyamoorthi et al (2008) and Sipai et al (2015).…”

“…These altogether resulted in to overall increase in the above characters. Similar findings were also observed by Patel et al (2013) and Sipai et al (2015). Harvest index varied significantly due to spacing, where highest value (26.36 %) was recorded at 30 x 10 cm spacing which was at par with 20 x 10 cm spacing and the lowest value (25.21 %) was observed at 20 x 10 cm spacing.…”

Seed bio-priming of green gram with Rhizobium and levels of nitrogen and sulphur fertilization under sustainable agriculture

“…Data showed that the significantly higher NPK and S uptake of ~ 37, 4, 7, 1.26 kg ha -1 in seed and the uptake of in stover ~ 15, 3, 28, 1.57 kg ha -1 of NPK and S, respectively. It may be due to the effect of symbiotic rhizobacteria augment nodulation in root and increased N-fixation and improve the availability of N and others nutrient in soil (Sipai et al, 2015).…”

“…Meanwhile in case of OC, available NP and S content increased (2, 4.5, 2 and 22%), respectively by application of 20 kg S as compared to control plot (Table 4). Available N and S content increased with increasing doses of S (Sipai et al, 2015). Bio-priming also influenced the available soil nutrients (Meena et al, 2016).…”

“…Nitrogen is the chief promoter of plant growth, however, in case of green gram, nitrogen does not usually show its effect, except that the vegetative growth is increased. However, the starter dose is required for initial growth (Sipai et al, 2015). Nitrogen is one of the most important primary nutrients among non-metal element which require in large quantity for the plant growth and nutrition (Lowenfels et al, 2011).…”
