A field experiment was conducted to study the influence of spacing on clusterbean varieties in alfisols of scarce rainfall zone under rainfed situation for consecutive three kharif seasons of 2013, 2014 and 2015 at the Agricultural Research Station, Ananthapuram of Andhra Pradesh. Pooled data revealed that higher yield was recorded with branched varieties (447 kg ha-1) than unbranched varieties (445 kg ha-1). Unbranched variety produced higher haulm yield. Among crop geometry, 22.5 x 10 cm recorded higher seed yield of 512 kg ha-1 while lowest seed yield of 393 kg ha-1 obtained with 45x10 cm. Among crop geometry tested, higher haulm yield was registered with 45x7.5 and 22.5x7.5 cm spacing resulted lowest haulm yield. Considering the economics and large scale availability of seed drills and planters with farmers sowing of cluster bean either branched or unbranched genotypes with 30 x 7.5 or 10 cm spacing was found optimum.

A field experiment was conducted during kharif, 2005 at Agricultural Research station, Devihosur, Haveri, Karnataka to assess the progress of powdery mildew at different time interval of sowing dates. Totally 20 different dates of sowings were imposed in the experiment at an interval of 10 days. The crop sown on last week of May to mid of June recorded minimum disease severity compared to rest of the date of sowings. This clearly indicated that crop sown during this period suffers less, which may be due to low inoculum potential, whereas late sown crop suffers more because of the readily available inoculum in the early sown crops. Low disease severity in last week of May to mid of June sowing may be attributed to the non-congenial weather factors for the development of the disease.

A field experiment was conducted at Main Agricultural Research Station, Dharwad during rainy season of 2015 and 2016 to study the effect of planting pattern and phosphorus management on production and profitability of intercropping system of mungbean and pigeonpea. The experiment was laid out in split plot design with three replications and eight treatments. Among them, four planting patterns [sole pigeonpea, mungbean + pigeonpea 1:3 (120 cm x 20 cm), mungbean + pigeonpea 1:2 (90 cm x 20 cm) and mungbean + pigeonpea 2:2 (90 cm x 20 cm)] were main plot treatments and two phosphorus levels (P2O5 @ 50 kg ha-1 and P2O5 @ 75 kg ha-1) were sub plot treatments. Based on pooled data the results revealed that, the significantly higher mungbean seed yield (424 kg ha-1) was recorded with application of 75 kg P2O5 as compared to 50 kg P2O5 ha-1. Whereas, in planting pattern, sole mungbean recorded significantly higher seed yield (757 kg ha-1) as compared to all other intercropping systems. Yield advantage indices and net returns were significantly higher in pigeonpea + mungbean (1:3) with 75 kg P2O5 ha-1 as compared to other treatments. This study indicated the need of fifty per cent higher dose of P2O5 for the pigeonpea and mungbean intercropping system (1:3) in northern transition zone of Karnataka.

The climatic situation in north eastern parts of Karnataka (except Bidar district) is almost similar to that of Rajastan. There is considerable area under rainfed situations and guar being a highly drought and temperature tolerant summer annual legume crop, there is hope for guar as an alternate and contingent crop during drought year in this region. With this objective effort were made to introduce, evaluate and to identify suitable gum guar varieties for North eastern parts of Karnataka. Ten gum guar varieties developed, released and cultivated in Rajasthan, Haryana and Gujarat state were evaluated in Agricultural Research Stations (ARS) located in Bidar, Gulbarga, Yadgiri, Bellary and Raichur districts of Karnataka during Kharif 2013-14. At Bidar, the top entry with respect to yield was HG-884 (679.00 Kg/ Ha), Variety RGC-1031 (793.00 Kg/Ha) performed well with respect to seed yield in Gulbarga district. Genotypes GAUG-13 (614.00 Kg/Ha) and RGC-986 (501.00 Kg/Ha) recorded higher seed yield respectively, in Bellary and Yadgiri district. At Raichur GAUG-13, recorded highest seed yield of 1432.00 Kg/Ha. Over the locations genotype GAUG-13 recorded highest seed yield of 759.00 Kg/Ha followed by HG-884 (700.40 Kg/Ha) and RGC-986 (696.60 Kg/Ha). The varieties tested exhibited considerable significance differences among themselves at four locations, except at one location (Agricultural Research Station, Bheemarayanagudi, Yadgir district). Variety GAUG-13, recorded highest seed yield over three locations indicating its wider adaptability.

Aim: To identify the best planting time for obtaining higher seed yield and quality of Soybean in off season. Study Design: Randomized completely block design (RCBD) Place and Duration of Study: Agricultural Research Station, Halladkere, Bidar, Karnataka between 2016 and 2017. Methodology: A field experiment was conducted at Agricultural Research Station, Halladkere, Bidar to find out the best off season planting time for quality seed production of Soybean. The certified seeds of soybean varieties, JS-335 and Dsb-21 were sown with recommended package of practices at appropriate field condition from November to February at every fortnight with a spacing of 30 cm X 10 cm. The quality parameters related to seed were carried out in the laboratory of seed science department. Further, soybean seeds were treated with fungicide (carbendazim 25% + mancozeb 75%) at the rate of 3 gram per kg of seeds. Results: From the present investigation, it was observed that among the different sowing dates, soybean varieties (JS 335 and DSb 21) sown during 1st fortnight of November recorded significantly higher plant growth parameters as well as seed yield followed by 2nd fortnight of November during off season. Further, climatic factors like rainfall, maximum and minimum temperature and relative humidity played a major role in the off season to produce higher seed yield and quality of Soybean. Conclusion: Among various sowing dates, November 1st Fortnight sowing resulted in highest seed yield with better seed quality in both cultivars (JS-335 and Dsb-21) of soybean.
