Abstract

The experiment was conducted at Dry Farming Research Station, Targhadia (Gujarat) to study the effect of bio inoculants (Compost culture, PSM and Azotobacter) and natural amendments (rock phosphate and iron pyrite) on nutritional composition of compost. The samples were drawn after 30, 60 and 90 days after composting. The organic carbon and C/N ratio decreased during maturation of the compost irrespective of treatments. At 90 days, minimum organic carbon (20.46%) and C/N ratio (9.39) was recorded with incorporate RP+MI+urea+Pyrite @ 5% on weight basis (T₆). Irrespective of treatments the total content of N, P, K S and micronutrients (Fe, Zn, Mn, Cu) were increased with advancement in maturity period of composting and their highest values were observed with RP @ 1% P₂O₅+MI (compost culture-Azotobacter, PSM) @ 500 g/t+urea @ 0.5%+Pyrite @ 5% on weight basis of crop residues.

Abstract

A field experiment was conducted at Dry Farming Research Station, Targhadia (Gujarat) during Kharif 1997-2002 to study the effect of crop residue recycling through organic mulches and their decomposition with varying levels of nitrogen on soil and crop productivity in groundnut-pearlmillet sequence under dry farming condition. It was noticed from results that mulching of farm waste found better for maintaining status of organic carbon, available nitrogen and potash while, wheat straw and groundnut shell found superior in case of available phosphorus and sulphur, respectively. Groundnut shell was found superior among various mulches in respect to physical parameters of soil.

Abstract

A field experiment was conducted for successive six years (2001 to 2006) at Dry farming Research Station. Targhadia (Gujarat) to study the response of oilseed crops (soybean, groundnut, sesame) to enriched and vermicompost on Vertic Ustochrept under rainfed conditions. There were four treatments comprised enriched compost @ 6 t/ha, 50% RDF+1 t/ha vermicompost, vermicompost @ 2t/ha and 100% RDF for respective crop. Maximum yield of soybean and groundnut were recorded with enriched compost @ 6 t/ha and that for sesame under 100% RDF. The application of enriched compost @ 6 t/ha was proved better for obtaining maximum uptake of N, P and K by soybean as well as groundnut and P and K uptake by sesame. Treatments involving enriched compost or vermicompost found beneficial in respect to availability of various nutrients at harvest.

Abstract

A field experiment was conducted during 1985 to 1996 on Vertic ustochrepts soils at Main Dry Farming Research Station, Targhadia (Gujarat) to study the effect of periodical application of phosphorus with and without FYM on content and uptake of nutrients by groundnut and soil fertility. The results revealed that the content of N, P and K in pod and haulm of groundnut and their total uptake as well as protein content were increased due to application of FYM and phosphorus. Significant positive effect of applied FYM was observed on status of organic carbon and available P, K and S in the soil. The organic carbon content and available status of potassium in the soil could not significantly alter due to periodical application of phosphorus. However, application of P was found beneficial in respect to available status of P and S in the soil.
