Comparative efficacy of cucurbitacin phytonematicides and Velum on growth and fruit quality of watermelon cultivar ‘Congo’ and suppression of Meloidogyne enterolobii under field conditions

The comparative efficacy of bio-organic nutrients on cropping behavior and fruit quality of kiwifruit was analyzed using farm yard manure (FYM), vermicompost (VC), biofertilizers (BF), green manure (GM), and vermiwash (VW). Among various treatments the combination of FYM at 15 kg/vine, GM, VC at 15kg/vine, BFat50-g/ vine and VW at 2kg/vine significantly improved cropping behavior. This superior combination also resulted in considerably greater amounts of leaf macro-and micronutrients: N (2.49%), P (0.26%), K (1.48%), iron (Fe: 208.0 mg/kg), copper (Cu: 17.8 mg/kg), zinc (Zn: 36.2 mg/kg), and manganese (Mn: 88.3 mg/kg),which might be responsible for better cropping behavior, productivity and nutrient profile for sustainable kiwi fruit production. It can be concluded that with use of various sources of bio-organic materials under organic farming regime, there will be sufficient improvement in fruit quality and plant nutrient contents.

Abstract Potassium is a mineral nutrient that affects the growth and quality of pineapple fruits. This study aimed to evaluate the quality of ‘Vitória’ pineapple fruits submitted to application of potassium doses. The experiment was carried out from May 2017 to November 2018, in the municipality of São Francisco do Itabapoana (RJ), Brazil. The design was randomized blocks, with four replicates. Treatments were five K2O doses: 0; 6; 12; 18 and 24 g plant-1, applied as KCl, split into two applications after flower induction. Fruit and crown fresh masses, fruit and crown diameters, fruit and crown lengths, titratable acidity, soluble solids, vitamin C, juice pH and soluble solids/titratable acidity ratio were evaluated. Potassium fertilization promoted greater fruit length, diameter and mass. Titratable acidity, soluble solids and vitamin C values increased linearly as a function of potassium doses. Potassium fertilization improves the quality of ‘Vitória’ pineapple fruits under field conditions.

Positive Effect

The purpose of this study was to evaluate effect of different fertilizer packages on the yield performance of cauliflower and tomato in the upland and hill valley. Influences of different fertilizer packages on yields and fruit quality of cauliflower and tomato were compared during 2015 to 2017 growing periods under field conditions. The experiments were conducted in two hill district of Bangladesh (CHTs) i.e Bandarban and Khagrachari under the AEZ 29 (Northern and Eastern Hills Tract). In this experiments Cauliflower and Tomato in the upland hill valley soil were used as the test crop. The experiment was designed on Randomized Completely Block Design (RCBD) with three replication. The treatments consider as Cauliflower: *T1= Farmers Practice, T2= N100P50K90 S18 Zn2.3 B0.5 kg/ha, Cowdung 5 ton/ha, T3= 125% of T2 and T4= 150% of T2. Tomato: *T1= Control, T2= N100P50K90 S18 Zn2.3 B0.5 kg/ha, Cowdung 5 ton/ha & lime 1.5 t/ha, T3= 125% of T2 and T4= 150% of T2. In khagrachari, the highest yield of cauliflower (44.98, 59.07 and 45.67 t/ha) and in Bandarban site (57.98, 53.47 and 55.66 t/ha) was recorded with T4 treatment that received 150% of T2 while the lowest yield was observed with T1 treatment receiving no fertilizer. In case of tomato, the highest yield (59.72, 55.73 and 36.07 t/ha) in Khagrachari site and in Bandarban site (56.43, 58.33 and 59.64 t/ha) was recorded with T4 treatment that received 150% of T2while the lowest yield was observed with T1 treatment receiving no fertilizer.
