Definitions
- the invention disclosed herein generally relates to plant nutrient compositions.
- the present invention relates to a plant micronutrient composition comprising transition metal phosphate and combination thereof
- Plants need certain essential nutrients for normal functioning and growth. Nutrient levels outside the amount required for normal functioning and growth may cause overall crop growth and health to decline due to either a deficiency or a toxicity. Plant nutrients are divided into two categories: macronutrients and micronutrients. Micronutrients are essential for plant growth and play an important role in balanced crop nutrition. They are as important to plant nutrition as primary and secondary macronutrients, though plants don't require as much of them. Millions of hectares of arable land worldwide, particularly in arid and semi-arid regions, are deficient in plant available micronutrients and this can markedly affect human nutrition (Graham and Welch 2000).

The experiment was laid out in RED with four replications. Two plants per replication per treatment were used for experiment. Standard check fungicides, Myclobutanil 10 % WP were purchased from local market. Sprays of these fungicides were given whenever the weather conditions were favorable for development of powdery mildew. Based on the favorable weather conditions five sprays were given for powdery mildew management, wherein, l ST two sprays were taken as prophylactic sprays. Water volume used for spray was calculated based on requirement of 1000 L/ha at full canopy. Knapsack sprayer was used for spray.
- Powdery mildew incidence on leaves was recorded visually adopting the 0-4 scale, where 0 means no disease present and 4 means more than 75 per cent leaf area infected.
- the ratings on ten leaves were recorded on randomly selected canes. Ten such canes per vine were observed, thus 100 disease observations were recorded per replicate. Four replications for each treatment were considered. Only actively growing powdery mildew lesions were considered for recording ratings.
- powdery mildew ratings are recorded separately on bunches. Powdery mildew incidence on bunches was recorded adopting 0-4 scale, where 0 means no disease present and 4 means more than 75 per cent bunch area infected. The ratings on twenty randomly selected bunches per replicate were recorded. During all the observations only active powdery mildew growth were considered for recording ratings.
- the yield data was recorded from the powdery mj Jdew trial.
- the marketable yield from the four replications of each of the treatments and the control was harvested and expressed in Kg grapes/vine.
- the POI data was transformed by using arcsine transformation for leaves and bunches and analyzed statistically following Randomized Block Design (RBD) using Statistical Analysis System (SAS software 9.3).
