Effect of growth regulators and micronutrients on fruit cracking and fruit yield in pomegranate

Abstract

A field experiment was conducted at Fruit Research Farm of Haryana Agricultural University, Hisar to evaluate the effect of micronutrients and plant growth regulators on fruit cracking and fruit yield in pomegranate cv. Jodhpur Red. The treatments comprising of two micronutrients (H3BO3 and ZnSO4 at 0.20, 0.40, 0.60 %), two growth regulators (2,4-D and NAA at 10, 20, 40 ppm) and water were applied fifteen and thirty days after fruit set. Occurrence of premature fruit cracking was more as compared to mature fruits during both the stages of application. Longitudinal (radial) cracking was more as compared to diagonal (transverse) cracking. 2,4-D and NAA at 10 ppm recorded significantly lower incidence of cracking than all other treatments. Highest fruit yield per acre (50.8 q) was obtained with NAA at 20 ppm when applied fifteen days after fruit set; while 2,4-D at 10 ppm recorded maximum fruit yield when applied thirty days after fruit set.

Efficacy of the liquid biological product on the growth and development of potatoes

“…Currently, a great number of various biological means, preparations and fertilizers for plant production are known. They include those for treating seeds, bulbs, tubers before sowing, as well as flooding and spraying in vegetation period (Kuldip Kumar et al 2017; Walid Fediala Abd El-Gleel Mosa et al 2017). A great variety of such products allows customers choosing this or that biological product according to individual criteria or combination thereof, particularly by their targets, composition, price, amount, consumption, storage conditions and duration.…”
