Field experiment was conducted at the Student's Research Farm, Department of Agronomy, Punjab Agricultural University, Ludhiana during rabi 2005-06 to evaluate the feasibility of different weed management options in bed planted wheat.

A pot experiment was conducted to study the toxic effect of nematicides: carbofuran, carbosulfan alone and their combination on soil microbial population and soil respiration with cotton as a test crop. The total bacterial population and free living diazotrophs population was reduced initially by nematicides application.

Potassium release kinetics was investigated in soils drawn from plots of a long term fertilizer experiment that had been receiving different rates of K. Non exchangeable K release was higher in soils that were receiving organic and inorganic fertilizers than the soils not dressed with K. The amount of non exchangeable K release was faster initially and it slowed down afterwards.

Carrot is one of the most popular and important vegetable cultivated and consumed throughout the world. It has been reported to have diuretic, nitrogen balancing properties and effective in the elimination of uric acid. In Northern India carrots, especially a variety that is deep purple in colour is fermented to make a traditional ready to serve drink known as Kanji.

An experiment was conducted to develop and evaluate energy and protein rich supplementary foods. Products namely Seviyan, Halwa, Pinjiri and Pinni were developed using combinations of germinated wheat and soybean and carrot powder for 4-6 years old children. Organoleptic evaluation, proximate principles, carotene, iron and calcium were determined using standardized methods.

Losses caused due to different insect pests under field conditions on four transgenic cotton hybrids (RCH 134, RCH 317, MRC 6301 and MRC 6304) were estimated in three districts of Punjab viz. Mansa, Ferozepur and Bathinda.

The study was conducted in three districts of Punjab to find out the indigenous techniques for management of insect-pests and their scientific background. It was revealed that several indigenous practices are useful for pest management and are relevant even in modern agriculture.

Studies on the population of key pests and natural enemies in RCH 134 Bt and non-Bt cotton hybrid under sprayed and unsprayed conditions were carried out under intercropped conditions. The cotton crop was intercropped with okra, pigeon pea, castor and cowpea to enhance the population build up of cotton jasid, whitefly, spotted bollworm and coccinellids.

A field trial was conducted during 2007-2008 crop season to study the effect of castor as a trap crop in cotton agroecosystem in relation to major insect pests. The treatments were 5, 10 and 15 rows of Bt cotton interspersed each with 1 row of castor, respectively, sole crop of Bt cotton and castor.
