Abstract
The present investigation entitled "Effect of biofertilizers and chemical fertilizer on growth, yield and quality of chilli (Capsicum annuum L.) cv. 'S-49' under Central Gujarat agro-climatic condition" was conducted during Kharif 2004-05 at the Horticultural Research Farm of Horticulture Department, B. A. College of Agriculture, Anand Agricultural University, Anand. A field experiment was laid out in Randomized Block Design with eleven treatment combinations and three replications consisting of different levels of nitrogen and phosphorus along with Azospirillum, VAM and Azospirillum + VAM. The result revealed that treatment T8 (75 kg N ha-1 + 37.5 kg P2O5 ha-1 + Azospirillum + VAM) produced significantly maximum number of branches plant-1 and plant height, which is followed by treatment T2 (75 kg N ha-1 + 50 kg P2O5 ha-1 + Azospirillum) and treatment T5 (100 kg N ha-1 + 37.5 kg P2O5 ha-1 + VAM) in number of branches at 2nd and 4th picking. While in case of plant height treatment T8 was at par with T2, T5, and T1 (100 kg N ha-1 + 50 kg P2O5 ha-1). It was also observed that treatment T8 registered minimum days taken for 50 per cent flowering, maximum yield per plant, yield per plot, yield per hectare, which is followed by treatment T2 and T5. Further, the maximum total numbers of fruit per plant was obtained under T8, which was followed by treatment T2 and T9 (50 kg N ha-1 + 25 kg P2O5 ha-1 ' + Azospirillum + VAM). The maximum fruit length and girth was observed under the treatment T8, which is followed by treatment T2 for length of fruit at 2nd and 4th picking and for fruit girth T2, T5 and T1, was at par at 2nd and 4th picking. However, initialplant stand at the time of 50 per cent flowering and final plant stand at harvest were found to be non significant. Looking to the finit quality aspects the highest TSS, capsaicin and acidity were recorded in treatment T8 followed by treatments T2, T9, T1, and T3 (50 kg N ha-1 + 50 kg P2O5 ha-1 + Azospirillum) for TSS, T2, T9 and T1 for capsaicin content and T2, T9, and T5 for acidity. as, moisture percentage which was found to be non significant. The economics of the various treatment combinations revealed that treatment T8 recorded the highest net realization as well as the highest cost benefit ratio as compared to rest of treatments. From the forgoing results, it can be concluded that, the seedlings should be inoculated with Azospirillum and soil application of VAM along with the application of 75 kg N ha-1, 37.5 kg P2O5 ha-1 gave the superior vegetative growth, higher fruit yield with good quality and net profit for vegetable purpose chilli under Central Gujarat agro-climatic condition.
