Opis:: Six experiments were conducted for the enhancement in seed cotton yield by increasing water use efficiency and water savings in case of different planting methods of cotton (Gossypium hirsutum L.) crop during the years 2014 & 2015, at three different locations in cotton zone of Punjab (Pakistan) province. The planting methods were, flat planting and no earthing up, flat planting and earthing up after 1st irrigation, flat planting and alternate row earthing after 1st irrigation, flat planting in 112.5/37.5 cm apart paired rows and earthing up after 1st irrigation, ridge planting and bed planting. Cotton crop obtained a maximum benefit from the available water at all three locations in case of flat planting with alternate row earthing up (P3) by predicting a maximum water use efficiency up to 6.79 kg ha-1 mm-1and maximum seed cotton yield of 3432.50 kg ha-1. Maximum water savings of 25.60% was recorded in the same method (P3) during the year 2014, while minimum (-0.17%) was observed in ridge planting (P5) at location number 1 in the same year.

Opis:: This study was designed to identify the response of oil and protein content to non-heritable variation of seed size in cotton (Gossypium hirsutum L.). The experiment was conducted at Gorgan University of Agricultural Sciences, Gorgan, Iran in 2005. The results showed that germination and emergence increased linearity with seed size and R2 of these relationships were 92 and 89%, respectively. This means that larger seed had higher potential of germination and emergence. Also, there was a strong linear relationship between seed weight and oil content. Seed weight provided a better indication of oil content (R2=0.78) than protein content (R2=0.43). There are no considerable relationship between seed size and protein content of seed...

Opis:: The cotton leafhopper (Amrasca biguttula biguttula Ishida) is considered to be an alarming insect pest causing both quantitative and qualitative loss in cotton. In situ bioassay studies were done and the role of detoxifying enzymes in conferring resistance to neonicotinoid groups of insecticides in low (MUD), medium (DVG), high (HVR) and very high (GLB) pesticide usage areas of Karnataka were determined. Bioassay studies showed that imidacloprid, thiamethoxam, acetamiprid, thiacloprid and clothianidin registered varying levels of resistance for all the locations studied. The resistance ratio was high in imidacloprid (3.35, 8.57, 9.15 and 12.27 fold respectively) and the lowest in dinoferuran (1.86, 5.13, 6.71 and 9.88 fold respectively). Furthermore, the enzyme activity ratio (glutathione-S-transferase) was relatively greater, and corresponded to the higher LC50 values of neonicotinoids for very high, high, medium and low pesticide usage areas. Our study suggested that the higher activity of the detoxifying enzyme in the resistance population of cotton leafhopper apparently has a significant role in endowing resistance to neonicotinoid groups of insecticides. However, this study recommends using neonicotinoids in cotton growing areas with caution.
