Abstract

A field experiment was carried out on loamy sand soil at Agriculture Research station Farm Derol, Anand Agricultural University, Anand, during Kharif 2010, to study the influence of organic and inorganic fertilizers on growth, yield, quality of soybean [Glycine max (L.) Merril] and soil properties. The experimental results revealed that an application of FYM @ 5 t ha^-1 recorded maximum plant height (99.69cm) , pod length (3.68cm), seeds per pod (3.08), seed yield (1,908 kg ha^-1), haulm yield (3,588 kg ha^-1), protein content (40.73%), oil content (19.59%), organic carbon (0.307%), available P₂O₅ (55.49 kg ha^-1) and available K₂O (245.38 kg ha^-1) than rest of the treatments. Application of inorganic fertilizer @ 100 % RDF (i.e 60 kg N: 30 P₂O₅: O kg K₂O) recorded significantly higher plant height (99.53cm) , pod length (3.71cm), seeds per pod (3.09), seed yield (1,868 kg ha^-1), haulm yield (3,537 kg ha^-1), protein content (41.21%), oil content (19.91%), organic carbon (0.310%), available P₂O₅ (56.26 kg ha^-1) and available K₂O (246.61 kg ha^-1).

Abstract

An experiment was conducted in summer season during 2008 at Anand Agricultural University, Anand. The soil was loamy sand in texture, low in organic carbon and available N, while medium in available P and high in available K. The treatment T₇ (Azospirillum+75% RDF+10 t ha^-1) recorded significantly higher plant height (171.41 cm). Similarly the total (6.48 plant^-1) and effective tillers (4.43 plant^-1) as well as length of earhead (22.25 cm) recorded significantly higher under the same treatment. The highest grain (4584 kg ha^-1) and straw (10084 kg ha^-1) yields were significantly registered under treatment T₇. Similar to yield, the significantly highest N and P uptake by grain (76.81, 28.9 kg ha^-1, respectively) and N uptake by straw (34.09 kg ha^-1) of pearl millet was observed under T₇ while it was true under T₂ in case of P uptake (29.67 kg ha^-1) by pearl millet straw. The highest net realization (Rs. 23885) was noticed due to 75% RDF+10t FYM ha^-1 including Azospirillum as bio-fertilizer application compared to net income of Rs. 21174 under fertilizer application at 100% RDF+10t FYM ha^-1. It is indicating more benefit besides reduction of chemical load i.e. 30 kg N and 15 kg P ha^-1 with the inclusion of bio-fertilizer.
