This research was done to find out the effect of increasing vermicompost application on yield of lettuce (Lactuca sativa L. var. crispa) plant. For this purpose Lactuca sativa L. var. crispa cv. Bellafiesta lettuce kind and Riverm Company vermicompost were used in this research. Four vermicompost doses (0 kg/ha, 4000 kg/ha, 8000 kg/ha and 12000 kg/ha) were applied to lettuce plant. According to the results, important increases of fresh weight, plant size, number of leaf, length and width of leaf for each plant and dry matter yield of plants were determined with increasing vermicompost applications. But the effects of Vermicopmost applications on some macro element (N, P, K, Ca and Mg) contents of plant were not found significant statistically.

The experiment was conducted at College of Horticulture, Mudigere to study the effect of fertigation on quality and biochemical parameters of strawberry fruits. The experiment consists of eight treatments, each treatment was replicated four times in Completely Randomized Design. Among the treatments, 100% recommended dose of fertilizer (RDF) through fertigation (T8) recorded significantly higher fruit yield per plant (384-391 g) and fruit quality parameters [fruit weight (17-18 g), fruit volume (18-19 cc), fruit length (4.00-4.14 cm) and fruit diameter (4.08-4.14 cm)]. However, it was at par with T7 (75% RDF through fertigation). With respect to biochemical parameters same treatment (T8) has recorded significantly higher values of all the parameters viz., reducing sugar (5.87%), non reducing sugar (1.96%), total sugar (7.87%), sugars: acid ratio (10.55), ascorbic acid content (69.27 mg/100 g) and titratable acid content (0.93%). Whereas, the total soluble solids (10.27 0B) were found the maximum in the treatment supplied with 25% RDF through soil + 75% RDF through fertigation (T6) and thus it can be concluded that T8 was the best treatment for improving the yield, quality and biochemical parameters of strawberry fruit.

The field experiment was conducted in Parasai–Sindh watershed to evaluate the groundnut yield (rainy season crop), water use efficiency (WUE) and economic value under different topographic condition of watershed, to improve the yield of the wheat crop (winter season), irrigation scheduling of improved irrigation method was compared with the traditional irrigation method. This Experiment was conducted from rainy season 2012 to winter season 2013.

The study was designed to determine the WUE, gross and net return under water scarcity area. The average yield (1205.33 kg ha-1); WUE [1.46 and 3.34 kg ha-1 mm-1 rainwater use efficiency (WUER) and effective rainwater use efficiency (WUEER), respectively] and benefit: cost (B:C) ratio (2.12) of groundnut were higher in upland as compared with lowland of watershed. Under sprinkler irrigation the yield and B:C ratio of wheat were improved 21.37 and 43.86% respectively as compared with conventional system (surface irrigation).  Sprinkler system of irrigation resulted in 32.21% less water used and 126.45% more economic water productivity (WPE) over conventional irrigation method in wheat.

A field experiment was conducted at All India Coordinated Research Project on Soybean, Main Agricultural Research Station, University of Agricultural Sciences, Dharwad, Karnataka, India to study the integrated nutrient management practices on red leaf index, insect pest and disease in cotton and soybean intercropping system in 1:2 row proportion during June 2016. The study was undertaken to evaluate the sources of nutrients to red leaf index and incidence of insect pest and diseases. The field experiment was laid out in randomised complete block design with three replications and twenty treatments. Treatment comprised of organic and inorganic sources of nutrients used in different combinations. Soybean introduced as intercrop in cotton with 40 x 10 cm spacing for soybean and 120 x 60 cm for cotton. Results found that there was no visual symptoms of leaf reddening at October 1st and lowest red leaf index was observed in T17 (T1 + Vermicompost 1.25 t ha-1 + Gliricidia 2.5 t ha-1). Lower incidence of Spodoptera larvae (Spodoptera litura Fabricius) was observed in T16 (T1 + Gliricidia 2.5 t ha-1 + Pongamia 2.5 t ha-1), T17 (T1 + Vermicompost 1.25 t ha-1 + Gliricidia 2.5 t ha-1) and T18 (T1 + Vermicompost 1.25 t ha-1 + Pongamia 2.5 t ha-1) at 40 DAS. Lowest pod borer (Cydia ptychora Meyr.) incidence was observed in T18 compared to other treatments. Lower per cent disease incidence of angular leaf spot of cotton was observed in T18 than other treatments at 85 DAS. Lower per cent disease incidence of Alternaria leaf blight of cotton was observed in T16, T17 and T18 compared to other treatments at 65 days after sowing. Integrated nutrient management in cotton and soybean intercropping systems reduced the red leaf index and provide resistance to crop to withstand against insect pest and disease.

Seeds of three roselle accessions (HS11, HS89 and HS41) were obtained from the Department of Horticulture, Kwame Nkrumah University of Science and Technology, Kumasi, Ghana and grown to obtain the calyces. The calyces were dried by sun (34.9°C), solar (56.5°C) and oven (60.0°C) methods. Most people consume the roselle calyces due to their nutritional and medicinal benefits. The study sought to, therefore, determine the effect of the different drying methods (oven, sun and solar) on the proximate composition of roselle accessions. The experiment was set up in a 3×3 factorial arrangement in a Completely Randomized Design (CRD) with three replications. The roselle accessions were harvested 12 weeks after sowing. From the results, HS89 had significantly (P ≤ 0.01) least moisture content of 8.43% and highest carbohydrate content (65.30%). Ash and protein contents were highest (P ≤ 0.01) in HS41 being 6.40% and 6.91%, respectively. As regards crude fat and crude fibre contents, HS11 had the highest being 2.49% and 17.92%, respectively. Concerning the methods of drying, oven-drying resulted in calyces with significantly (P ≤ 0.01) lower moisture content (6.97%), but higher fat (2.88%), ash (5.80%) and carbohydrate (62.46%) contents. solar-dried calyces had significantly higher (P ≤ 0.01) protein content (5.86%) while sun-dried calyces had significantly higher (P ≤ 0.01) crude fibre content (17.60%). Interactively, oven-dried HS89 had significantly (p≤ 0.01) lowest moisture (6.50%) and highest fat (3.23%) while solar-dried HS41 had highest protein (8.17%) and ash (7.25%) contents. The study concluded that oven drying was more efficient than solar and sun in reducing the moisture, maintaining fat, ash and carbohydrate contents of roselle calyces. Solar drying resulted in higher protein content while sun-dried calyces produced higher fibre content in all the three accessions.
