A field experiment was conducted in skeletal soil during Kharif season for two consecutive years of 2007-08 and 2008-09 at Dindori district of Madhya Pradesh to evaluate 8 intercropping system in kodon millet and pigeonpea. Sole kodon millet and pigeonpea gave highest yield. Association of short duration kodon millet cv DPS-19 and medium duration spreading type pigeonpea cv No. 148 in 2:1 rows proved to be best intercropping system with regard to total productivity of 4151 kg/ha in terms of kodon millet equivalent yields and land equivalent ratios of 1.60. Economics of the treatment significantly fetched maximum gross monetary returns (' 33316/ha), net monetary returns (' 18124/ha) and benefit-cost ratio (2.19) among all intercropping systems as well as sole cropping of either crops.

Integrated nutrient management (INM) involves efficient and judicious supply of all major and micro components of plant nutrients including local available resources on sustainable basis. Papaya is known to be a heavy feeder of nutrients (NPK) and information regarding the effect of INM is rather rare. Hence, an experiment was conducted at Department of Horticulture, Allahabad Agricultural Institute-Deemed University, Allahabad during 2005-06 and 2006-07 to study the response of Integrated Nutrient Management on growth, yield and quality of papaya cv. Surya. The experiment was laid out in randomized block design with four replications. The treatments comprised of recommended fertilizers dose (RDF) i.e. N:P:K - 200:250: 250 g plant-1, farmyard manure 50 kg plant-1, vermicompost 20 kg plant-1, poultry manure 20 kg plant-1; rhizosphere bacteria culture 50 g plant -1 alone and in combination with reduced levels of RDF viz. 75 and 50%. The yield of papaya was statistically at par with 75% recommended fertilizers rate + 25% vermicompost + rhizosphere bacteria culture in comparison to control (recommended fertilizers dose). Quality parameters of the fruits were found to increase with decreasing level of chemical fertilizers. Maximum number of leaves (18.73), trunk girth (0.26 m), number of fruits per plant (46), average fruit weight (0.85 kg), pulp thickness (3.5 cm), shelf life of fruit (12 days), vitamin A (2280 IU/100 g pulp) and TSS (15.8°Brix) were recorded with 75% RDF + 25% vermicompost + rhizosphere bacteria culture treatment, while maximum plant height (185.35 cm) and petiole length (8.42 cm) were associated with 100% RDF alone. The treatment of 75% RDF + 25% vermicompost + rhizosphere bacteria culture was found superior and economically viable than rest of the treatments.

Watershed is an ideal unit for planning and management of land and water resources (Gajbhiye et al. 2013). Watershed prioritization on the basis of soil erosion has become inevitable component of watershed management in order to conserve this precious natural resource. In the absence of sediment yield data, a Sediment Yield Index expressing the relative sediment yield on the basis of grading the basin or watershed in order of priority for soil and water conservation measures. The study area is divided into 15 sub-watersheds on the basis of drainage conditions. Sediment Yield index has been calculated for all the fifteen sub-watershed, following the All India Soil and Land Use Survey (AISLUS) method and accordingly prioritized. The maximum SYI value of 1337.36 is recorded for Mohgaon (MG)-12 sub-watersheds and minimum value of 846.58 is in Mohgaon (MG)-11 sub-watersheds. © 2014 SERSC.

A field experiment on effect of promising insecticide against pod bug Clavigralla gibbosa Spinola on pigeon pea was carried out during kharif season of 2012-13 at the Department of Entomology, Live Stock Farm, Adhartal, J. N. K. V. V., Jabalpur (M.P.). The experiment was laid out in randomized block design with three replications. Pod bug is one of the important pests of the pigeon pea in India. Its adults and nymphs suck the sap from the flower buds and developing seeds by piercing through the pod wall and harm the crop. For the management of this pest the six promising insecticides were tested along with control. Among the insecticides tested Rynaxypyr 20% SC @ 30g a.i. /ha was found to be most effective as it recorded lowest bug population after each spray intervals. Novaluron 10% EC @ 75 g a.i./ha was proved lesser effective to reduce the bug population in the pigeon pea.

The aim of this study is to form an analysis of nonlinear stochastic models in soybean production in Madhya Pradesh and India. The data set used for this analysis was taken from soybean processor association (SOPA) Indore. Eight nonlinear stochastic models were taken: Gompertz, Logistic, Richard, Janoschek, Champman, Morgan-Mercer-Flodin (MMF), Boltzmann and Weibull. For model fitting performance, we used four comparison criteria; coefficient of determination (R2), sum of Squares of error (SSE), root mean squares error (RMSE) and mean relative error (MRE). The results indicated that Weibull and MMF model are more useful than other non-linear models to estimate soybean production in Madhya Pradesh and also in India.
