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 present study is to describe the descriptive and growth rate study for some time series production factors of soybean and also making a diagnostic study for detecting some influential time series production factors governing total soybean oil production in India and also in Madhya Pradesh. The secondary data is recorded from soybean processor association Indore. In the path coefficient analysis, soybean area, production, productivity, price, number of oil plant in operation and total soybean expelled are considered as causal factors and their direct and indirect effect on soy oil production are estimated for India and also for Madhya Pradesh. The conclusion of this study indicates maximum growth in soybean oil production, minimum growth in soybean yield, most stable factor is number of oil plant in operation. The most direct influential factor for soybean oil production in India is soybean area and indirect influential factor is price of soybean. The most direct influential factor for soybean oil production in Madhya Pradesh is price of soybean and indirect influential factor is soybean production.

Quantitative analysis of agricultural production system has increasingly become the basis of agricultural policies in many countries. In the near future, efficiency improvement at farm level would probably be an appropriate way to increase soybean production. The policy maker attempt to enhance the uptake of important technologies relevant particularly to the small scale agricultural production by improving research and development process. It enables the farmers to improve their technical efficiency in production. This effort is based on the analysis of technical efficiencies in production of soybean crop by farmers of Madhya Pradesh. The aim of present study is to evaluate technical efficiency of particular farm and to observe up to what extent its efficiency can be increased without inclusion of any additional resources. The result shows a comparison of the small, medium and large farmer's variability. Technical efficiency is less in medium and lesser in small farmers and maximum in large farmers. Mean technical efficiency is high in large farmer as compared with medium and small farmers.

Coriander (Coriandrum sativum L.) has been cultivated for a long time in different parts of India and the world. This study aimed to identify the role of coriander seeds towards improved nutrition, which is essential for biological processes. The present investigation was carried on 64 coriander genotypes to identify the traits associated with seed yield and their attributes. Results revealed that seed yield plant-1 exhibited a positive and significant correlation with number of fruits umbel-1 but negative correlation with days to 50% flowering and days to 80% maturity. Almost all genotypes studied revealed diverse properties, making them suitable genetic materials for breeding homogenous coriander cultivars. Our research goal was to elucidate the diversity of agronomic, physiological and yield traits in coriander. In the present investigation, genotypic correlation coefficients were higher than the phenotypic ones because of the masking effect of genotypes for the expression of characters. Seed yield plant-1 exhibited a positive and significant correlation with number of fruits umbel-1 but was negatively correlated with days to 50% flowering and 80% maturity, whereas number of fruits umbellet-1 expressed a positive significant correlation with number of fruits umbel-1 and 1000-seed weight. A positive correlation was also noted between 1000-seed weight and number of fruits umbel-1. © Society for the Advancement of Breeding Research in Asia and Oceania (SABRAO) 2015.

The local farmers possess an immense knowledge of their environment. An effort was made to carryout a research on the conservation and testing of nitrogen effect over the location specific indigenous paddy varieties in purposively selected tribals' villages from Dindori Developmental Block of Dindori district, Madhya Pradesh. The results indicate that tribal farmers have developed location specific knowledge to identify varied micro-farming situations and accordingly they grow and conserve number of indigenous paddy varieties. Study suggests that instead of macro, the micro level of planning of research and conservation strategy would be required for sustaining the biodiversity and related socio-ecological systems.

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.

Farmers in Central India practice a unique rain water management system ('Haveli') based on impounding rain water in the fields during three months monsoon season (June-September) and draining out in October. Winter crops, mainly grain legumes are then grown that utilize the soil moisture conserved in the soil profile. We monitored the soil physico-chemical and fertility properties, C and N mineralization, microbial populations and biomass and soil enzymes in the 0-30cm soil layer at ten sites over three years at four stages viz., prior to submergence in summer (PS), during water-logging (WL), after drainage (AD) and after legume cropping (AC). Anaerobic conditions during water-logging (for 11 weeks) led to extensive losses of soil carbon amounting to 1900mgCkg-1 soil but no significant change in soil N. Post-drainage and decomposition of weeds (for 6 weeks), there was an increase in soil C of 3700mgCkg-1 and soil N of 74.1mgNkg-1 soil. Overall in 17 weeks, there was a net increase of 1800mgCkg-1 (+30.5%) and 87.5mgNkg-1 (+20.1%) amounting to soil C and N accretion rate of 15.1mgCkg-1 soilday-1 and 0.74mgNkg-1 soilday-1. Microbial biomass decreased by 19.7% during 11 weeks of water logging and improved by 54% in the 6 weeks aerobic phase; an overall increment of 23.5% (31mg microbial Ckg-1) in 17 weeks. Prolonged water-logging induced severe stress on microbial processes. However, post-drainage, there was significant improvement in microbial populations, nitrogen mineralization, soil enzymes and soil fertility. There were strong relationships between soil enzymes and microbial carbon; and, nitrogen mineralization and soil carbon. Results unequivocally demonstrated the benefits of rain-water conservation in Vertisols for carbon sequestration and nitrogen accretion and improvement of soil biological quality. © 2014.

Geomorphological parameters directly or indirectly reflect almost entire watershed based causative factors affecting runoff and sediment loss/soil erosion. So, in the absence of sufficient hydrological data morphometric parameters along with satellite based land use/land cover information of watershed may be helpful in prioritizing the sub-watersheds. Keeping these aspects in view, it was planned to develop a geomorphological index in the Shakkar river catchment of Upper Narmada Basin, India, The objective of the present study is to develop the Geomorphological Index using Principal Component Analysis on the morphometric parameters derived from the Geographic Information System (GIS) environment, which can be used by the field investigators and modeler’s in assessing the soil erosion. As an outcome of the analysis, the geomorphological index synthesizes the status of the three morphometric parameters i.e. drainage frequency (Fs), form factor (Rr) and bifurcation ratio (Rb) into a single indicator of geomorphological index. The Geomorphological Index (GI) for the study area found to vary from 3.64 to 21.63. The implementation of geomorphological index may provide the guiding data for sustainable water-resources management in Shakkar river watershed. © 2015, Geological Society of India.
