Growth and survival of budded Kinnow plants as influenced by different types of black polybags and soil media

The experiment was carried out to standardize the black polybags with different soil media for production of budded Kinnow plants with treatments comprising four different sizes of black polybags and different soil media containing soil, sand, vermicompost and farm yard manure (FYM) in different proportions. The interaction effect of different potting material and propagation media showed that potting material viz....

Effect of plant bio-regulators on vegetative growth, yield and quality of strawberry cv. Chandler

The results of effect of plant bio-regulators on yield and yield attributing characters of strawberry CV. Chandler showed that at 75 DAT the plant height attained maximum of 20.50 cm, spread (25.53 cm) leaf number per plant (23.00), petiole length (0.20 cm), leaf area (136.30 cm2) and yield (356.56 g/plant) respectively, of strawberry was obtained highest with the application of GA 75 mg/L while, cycocel 750...

Soil water crop modeling for decision support in millet-based systems in the Sahel: a challenge

Food insecurity in the Sahelian environment was extensively shown to be a result of low soil fertility and high climate risks. But decisions and recommendations made from the great wealth of research have little been adopted by farmers. Soil water crop models (SWCM) can assist researchers and development actors in this environment if they can appropriately deal with the constraints and mainly farmers’...

Chlorophyll and macronutrients content in leaf tissue of Musa sp ‘Prata-Anã’ under fertigation

The banana (Musa sp.) crop is notable for its social and economic importance in tropical and subtropical regions of world. In Brazil, despite being a main banana producer, its production is considered low, mainly due to water and nutrient shortages in soils. This fact motivated this study; so, it aimed to evaluate chlorophyll and macronutrients content in leaf tissue of banana ‘Prata-Anã’ (AAB) under...

Choice of alternative crop enterprises among smallholder tobacco farmers in Teso District, Kenya: A multinomial logit analysis

The study analysed the factors affecting the choice of alternative crop enterprises among smallholder tobacco farmers in Teso district, Kenya, using Multinomial logit model. Data used for the study were obtained from primary sources through structured questionnaires using a multistage sampling technique from 150 farmers selected randomly. The results indicate that farmers are indeed reducing the acreage under tobacco...

Determinants and incentives for soil conservation on farms in Central Gujarat: An empirical study

The present study examined the effect of incentives in crop production and identified the determinants of incentives on farmers in Central Gujarat. The real domestic prices of the pearl millet, the major crop, moved in tandem with incentive component over time. But this incentive failed to provide push to the crop productivity of pearl millet during the period. The real domestic price of pearl millet declined during the...

Microcalorimetric study of microbial activity changes of acrisol in subtropical China under three different land management

The microcalorimetric method was applied to analyze the influences of successive reforestations with Eucalyptus granddis × E. uophylla, Pinus massoniana, and continuous sugarcane production on the soil microbial activities. 500 g of each refined representative sample was collected in rainy and dry seasons from four 100 m2 homogeneously and perfectly defined acrisol quadrats in subtropical China. Two of them were...

Effect of growth conditions on reducing properties of maize (Zea mays L.) root exudates

In the present study, impacts of nitrate/ammonium ratios, aluminum and phosphate stress on the reduction properties of five-leaf maize root exudates were investigated using hydroponic culture method. Appropriate nitrate/ammonium ratio (3:1) prompted maize roots to secrete more organic reducing substances which led to more release of Mn2+ from MnO2. Under stress of low phosphorous and high aluminum, maize roots release...
