A field investigation entitled "Effect of plant geometry and nutrient levels on productivity of Bt cotton" was conducted during kharif season of 2009-10 at AICRP for dryland agriculture, Marathwada Agricultural University, Parbhani. The experiment was laid out in split plot design with three replications. There were twelve treatment combinations comprising three plant geometries viz., 90 cm x 60 cm, 120 cm x 45 cm and 180 cm x 30 cm and four nutrient levels viz., 80:40:40, 100:50:50, 120:60:60 kg NPK/ha and 75 % RDF + 5 t FYM/ha. The plant geometries are allotted to main plot and nutrient...

Studies were carried out on seasonal incidence, screening of genotypes and bio-efficacy of insecticides against pest complex of brinjal (Solanum melongena L.) at Regional Horticultural Research Station Farm, NAU, Navsari during 2011-12. The results revealed that the incidence of sucking pests viz., jassid (Amrasca biguttula biguttula Ishida) started from November (3.20 jassids/three leaves) and reached to a peak level (22.46 jassids/three leaves) during December, whereas whitefly (Bemisia tabaci Gennadius) started from November (7.27 whiteflies/three leaves) and reached to a peak level (25.73...

Investigations on population dynamics, varietal screening and chemical control of leaf webber, Cydia critica (Meyrick) of pigeonpea was carried out at Instructional farm, College of Agriculture, Junagadh Agricultural University, Junagadh, during the kharif-rabi season of the year 2008-09. While study on bionomics of C. critica was carried out under the laboratory conditions at Department of Entomology, College of Agriculture, Junagadh Agricultural University, Junagadh, during kharif 2008. The larva formed web by folding the leaf lamina from mid-rib and scarified the lamina, culminating a...

the "Influence of levels and sources of sulphur on yield, quality and chemical composition of soybean in sandy loam soil." The soil under the field experiment was deficient in available S (8.5 mg Kg-1) and neutral to slightly alkaline in reaction. The S sources evaluated under the study were S1: Gypsum (G), S2: Elemental Sulphur (ES) and S3: Single Super Phosphate (SSP). The levels kept were L1: 0 kg ha-1, L2: 20 kg ha-1 and L3: 40 kg ha-1. The experiment was laid down in a Factorial Randomized Block Design with four replications. The results revealed that the plant stand at the initial stage...

Mushroom are fungi which lack chlorophyll and can not manufacture their own food in the presence of sunlight as to green plants. However, mushroom can produce a wide range of enzymes that degrade the complex. substrate on which they grow, following which they absorb the soluble substance for their own nutrition. In this country mushroom is grown in the largest quantity in Himachal Pradesh. There is an organization named NCMRT made a survey to sort out problem faced by the farmers. The more mushroom will be popular the more facilities will be extended to the farmer for its intensive and...

The design principle of water harvesting structures is similar to other hydraulic structures requiring wide range of input. In many regions of local thumb rule are used for designing the structures. For hydrologic design a more or less universal criterion is followed which is basically, ― the ratio of the catchment area to the cultivated area. The failure of such structures is mainly due to insufficient hydraulic capacity and lack of provision for dissipating energy of falling water into the structure. That is why, design of these structures is done considering not the discharge...
