The investigation was undertaken with a view to determine the “Effect of foliar spray of various micronutrients on growth, yield and quality of papaya (Carica papaya L.) cv. Madhu Bindu” and results revealed that the individual application of ZnSO 4 0.5% and borax 0.3% exerted great influence on plant height, stem girth and number of leaves as well as earlier initiation of flower bud and minimum days taken from fruit setting to first harvest. The yield characters i.e. average weight of fruit, number of fruit and yield of fruits per plant with maximum yield per hectare was also recorded maximum with ZnSO4 0.5% and borax 0.3% when the plants sprayed at 30, 60 and 90 days after transplanting. In quality point of view, different levels of ZnSO4 and borax had markedly influenced the quality of papaya fruits i.e., ascorbic acid (mg/100g), total soluble solids (%), reducing sugar (%), non-reducing sugar and total sugar (%).

Background: Novel organic liquid Nutrients have been developed based on banana pseudostem comprising of 10 macro and micro nutrients and 2 hormones, which are naturally synthesized. It is developed by Navsari Agricultural University, Navsari in Year 2009-10 under management and value addition of banana pseudostem (NAIP-II) project. To know the extent of adoption of Novel organic liquid nutrients in fruit and vegetable crops, a study was formulated to know the correlation of different factors and characteristics for adoption of the product. Methods: This study was conducted in the Vyara, Valod, Songadh and Dolvan blocks of Tapi district of Gujarat through Krishi Vigyan Kendra, NAU, Vyara, Tapi during 2018-19. In the study, the sample size was of 100 respondent were selected through stratified random sampling method and determine the correlation of dependent and independent variable on knowledge and adoption of Novel organic liquid nutrients in fruits and vegetable crops. Result: In this study revealed that the adoption of Novel organic liquid nutrients up to 59 per cent in fruit crops and 76 per cent in vegetables crops among farmers. The data on correlation for extent of adoption of Novel organic liquid nutrients in fruits and vegetable crops were showed significantly results with education, training and knowledge at 5 per cent (0.1965) level of probability.

An experiment laid down to evaluate the effect of biofertilizers, growth regulator gibbralic acid (GA₃) and micronutrients on yield and yield attributes of Sapota cv. Kalipatti at Fruit Research Station, Navsari Agricultural University, Gandevi, Gujarat. The treatments of recommended dose of fertilizer (RDF), i.e.100 kg FYM and 1000:500:500 g/plant NPK along with application of biofertilizers (Azospirillum + PSB), growth regulator (GA₃) and micronutrients. The pooled results of 75% RDF + biofertilizers- Azospirillum + PSB @ 40 ml/tree + GA₃ @ 50 ppm + Grade 4 (micronutrient @ 0.5%) were exhibited significantly higher number of fruit (2815.45), yield (20.61 t/ha)along with net return (Rs. 3,03,951/ha) and Benefit Cost Ratio (2.81). The said application enhanced fruit yield up to 43.41% over control comprising RDF only. However, significantly higher fruit weight (81.34 g) was recorded in application of 100% RDF + biofertilizers- Azospirillum + PSB @ 40ml/tree + GA₃ @ 50 ppm + Grade-4 (micronutrient @ 0.5%).

The study was conducted on marketing behaviour of 100 okra growers from two talukas of the Tapi district by simple random sampling technique. The findings of marketing behaviour of farmers revealed that 75 per cent used bike for transport their produce, 75 per cent used plastic bags as packing material and majority of the farmers sold their produce immediately after harvest in the nearby market. Whereas, 81 per cent farmers reported that they received full payment on the spot after sale. Agriculture Produce Marketing Committee (62%) was important source of market information. Major problems in the marketing were price fluctuation (100%), high cost of cultivation (83%), poor quality of seed (69%) and climate change (21%) as well as export of okra very less extent. Independent variable training and experience significantly correlated with the yield of okra. However, regression clearly indicated the importance of experience and training in the farming and marketing of okra.
