Abstract

The present experiment was conducted to assess the morphological and yield attributing characters of twelve Indian jujube (Ziziphus mauritiana L.) cultivars using randomized block design with three replications during the year 2017-18 and 2018-19 at University of Agricultural Sciences, Raichur, Karnataka. A sum of seventeen morphological and yield attributes of shoot, leaf, flower, fruit and yield related parameters were studied. The results revealed significant variability across the ber cultivars for all the parameters. Among the cultivars, Sanaur-6 showed maximum canopy volume, highest number of productive shoots, widest leaf, longest fruit length, fruit width and fresh weight of fruit. Cultivar manuki produced highest number of flowers per cluster and yield per hectare. Therefore, these identified cultivars could be considered as prominent for cultivation or to exploit as a source of desirable cultivars in future ber improvement programme. [ABSTRACT FROM AUTHOR]

Abstract

Nutrient requirement for guava under high density planting is much higher than normal planting. Combined application of organic manures and chemical fertilizers will enhance nutrient use efficiency. The field experiment was carried out at Raichur, Karnataka, India during 2017 to standardize rate of fertilizers and organic manures for Guava (Psidium guajava L.)  cv. Allahabad safeda under high density planting. Treatments consists of application of fertilizers for normal planting compared with 100:40:75 g NPK/plant as recommended dose of fertilizers (RDF), 75% and 50% of high density planting (HDP) along with 25 kg farmyard manure, organic manure alone and foliar application of urea @ 1 % at 2,3 and 4 months after pruning. Results indicated that application of NPK@ 235: 118: 120 g per plant as per the RDF for HDP along with 25 kg FYM has resulted in taller plants, plant spread E-W as well as N-S directions, canopy volume and leaf area index. Higher fruits/plant, average fruit weight, fruit diameter, fruit length, fruit yield per plant and fruit yield (48.58 t ha-1) was recorded by application of NPK@ 235: 118: 120 g per plant same as that of HDP along with 25 kg FYM. Application of 50 % of HDP recommendation along with foliar application of urea @ 1% at 2, 3 and 4 months after pruning and 25 kg FYM was also found effective in achieving higher fruit yield of guava.
