ABSTRACT: Kinnow (Citrus reticulate Blanco) fruit is one of the best commercial fruits of Pakistan. It is cultivated on a large area in the Punjab province due to its reasonably higher yield, quality, taste and flavor than those of the other citrus fruits. However, its average yield in Pakistan is far below than that of the other citrus growing countries of the world. Fruit dropping is one of the main reasons of low citrus fruit yield in Pakistan, which is thought to be mainly due to hormonal imbalance in the plants. This imbalance may occur as a result of nutrient deficiency in orchard soils, water shortage, and insect pest attack on the citrus trees. Therefore, experiments were conducted to assess the influence of growth regulators [2,4-D and salicylic acid (SA)] and nutrients [potassium (K) and zinc (Zn)] to improve yield and quality of Kinnow fruit and control the fruit drop at four selected sites in the citrus growing tract of Punjab, Pakistan. Foliar applications of 2,4-D, SA, K, and Zn significantly improved the fruit weight, number of fruits per plant juice percentage, total soluble solids (TSS), ascorbic acid content, acidity, and TSS/acid ratio, and reduced the fruit drop. Application of 2,4-D+K+Zn and SA+K+Zn showed beneficial effects on all the afore-mentioned parameters.Pakistan Journal of Botany 01/2013; 45:433-445. · 0.87 Impact Factor

ABSTRACT: Investigations to assess the growth and yield response of three wheat varieties (Inqalab-91, Kharchia and Parwaz-94) to different seeding densities i.e. 100, 125 and 150 kg ha-1 were carried out on a sandy loam soil. The results indicated that seeding densities significantly affected various growth and yield parameters like germination count, total number of tillers m-2, number of grains spike-1 and grain yield, but total leaf area plant-1, straw yield and harvest index were not affected significantly. The varieties differed significantly from one another with respect to the yield and yield contributing parameters. Wheat variety Inqalab-91 when sown @ 150 kg ha-1 gave the highest yield.
