Seedlings on Different Substrates <p>The substrate is one of the most important factors in the formation of the seedling and must present conditions suitable for germination and development of the seedling root system. The objective of this work was to evaluate the effect of different substrates on the initial growth of <em>Physalis peruviana</em> L. seedlings. The experiment was conducted at the Experimental Farm, of the Federal University of Espírito Santo– São Mateus (Brazil). The experimental design used was completely randomized, with three treatments (Soil, Provaso® and Bioplant®), seven replications and seven plants per plot, using seeds with 427 days of storage. At 56 days after sowing, the 10 most vigorous seedlings were selected for evaluation. The following characteristics were evaluated: percentage of emergence, emergence speed index (ESI), mean time of emergence (MET), number of leaves (NL), stem diameter (SD), aerial part length (APL), aerial part fresh matter (APFM), aerial part dry matter (APDM), root fresh matter (RFM), root dry matter (RDM) and Dickson quality index (DQI). The Provaso® substrate showed the best performance in all studied variables, being recommended for the production of <em>Physalis </em>seedlings.</p> Jeniffer Ribeiro de Oliveira, Mayara Nascimento Santos, Joabe Martins de Souza, Vinícius de Souza Oliveira, Mariana Alexandre Alves Amourim ##submission.copyrightStatement## Thu, 02 Jul 2020 00:00:00 +0000 Impact of Foliar Fertilization on Leaf Nutrient Status of Kinnow Mandarin <p><strong>Aims:</strong> To study the impact of Urea, K<sub>2</sub>SO<sub>4</sub>, ZnSO<sub>4</sub>, FeSO<sub>4</sub> and boric acid on leaf nutrient status of Kinnow mandarin.</p> <p><strong>Study Design: </strong>The experiment was performed in randomized block design with three replications per treatment on Kinnow mandarin.</p> <p><strong>Place and Duration of Study:</strong> The current study was carried out on seven years’ old earmarked plants at the Horticultural Orchard and in Soil Testing Laboratory of College of Agriculture, CCS Haryana Agricultural University, Hisar during the year 2016-17.&nbsp;</p> <p><strong>Methodology: </strong>The eleven fertilizer treatments in different combinations of Urea, K<sub>2</sub>SO<sub>4</sub>, ZnSO<sub>4</sub>, FeSO<sub>4</sub> and boric acid were arranged in randomized block design with three replications on seven years old uniformly grown Kinnow mandarin trees.

The main objective was to determine the effectiveness of vermicompost and biochar on growth and yield of carrot. The experimental design applied was randomized block design (RBD) with three replicates for each treatment. The eight treatments comprised of T1- (Control), T2- (100% NPK), T3- (100% Biochar), T4- (50% Biochar + 50% NPK), T5- (75% Biochar + 25% NPK), T6- (100% Vermicompost), T7- (50% Vermicompost + 50% NPK), T8- (75% Vermicompost + 25% NPK). The growth parameters <em>i.e.</em> plant height, number of leaves, root length, root diameter and yield parameter fresh weight of root were analyzed during growth period and final harvesting in carrots for each treatment using standard methods. The results showed that vermicompost and biochar had a positive effect on all the parameters. T7- 50% Vermicompost + 50% NPK recorded highest yield of 27.67 t/ ha, while the lowest yield (12.24 t/ ha) was recorded in T1- (Control) from the carrots which did not receive any nutrients. However, yield recorded in T4- 50% Biochar + 50% NPK was at par with T8- 75% Vermicompost + 25% NPK. On the basis of the results of this study, 50% Vermicompost + 50% NPK is therefore recommended because it improves the growth parameters resulting to higher yield in carrots.</p> P. Biswas, B.

Six different varieties like Sahabhagi dhan, Mandakini, Jogesh, DRR-44, and DRR-42 &amp; Khandagiri were taken with four replications in Randomized Block Design in both years. Technology demonstration included not only the improved short duration varieties, but also a package of good agronomic practices <em>viz.</em> line sowing, seed treatment with Bavistin, proper fertilization with dose @ 80:40:40 NPK/ha, pre emergence herbicide application with pretilachlor, needful manual weeding and&nbsp; need based plant protection chemicals. The results of demonstration showed that farmers could increase rice productivity notably by adopting improved variety <em>Sahabhagi dhan</em> and <em>DRR-44</em>. These varieties recorded higher grain yields of 64% and 46%, respectively, and fetched a sum return of Rs 25620 and Rs 25275 over farmers’ local variety <em>Khandagiri.</em></p> S. Pradhan, F. H.

Maize (<em>Zea mays</em> L.) variety Longe IV was the test crop. A Ferralsol from northwestern Uganda (West Nile) was used in this study.</p> <p><strong>Results and Conclusion:</strong> Mehlich 3 correlated most with plant P uptake by presenting the highest correlation coefficient with plant P content (r = 0.254) and a number of leaves per plant (r = 0.733). A strong positive correlation existed between Bray I and Mehlich 3 extractable P values (r = 0.975), suggesting lack of a marked difference between them; implying that either of the two procedures could be applied for soil P extraction in Ferralsols. However, Mehlich 3, being a multi-nutrient extractant, was recommended as the most suitable for P extraction for the Ferralsol used in this study.</p> J. S. Tenywa, E. Odama, A. K.

The design adopted was Randomised Block Design (RBD) having ten replications with four treatments. The different forms of boron treated cauliflower plants attributed higher yields over control. Among different treatments evaluated, the treatment T3 <em>i.e.</em> FYM @ 10 t/ha + Boric acid (20% Boron) @ 0.3% as foliar spray after one month of planting showed better yield (91% fresh curd harvested) and quality in respect to curd size (24 cm) and weight (2.70 kg) followed marginally by T4 <em>i.e.</em> FYM @ 10 t/ha + Total B<sub>2</sub>O (liquid Boron - 20% Boron) @ 1.5 g/L of water as foliar spray after one month of planting in all aspects followed by T1 <em>i.e.</em> Farmyard manure @ 10 t/ha as basal dose and T2 <em>i.e</em>. FYM @ 10 t/ha+ Borax @ 15 kg/ha as basal dose respectively. Treatment T3 also achieved 13.41%, 51.66% and 139.47% more fresh curds as compared to T4, T2 and T1 respectively. Treatment T4 showed improved performance (82% fresh curd) after T3 which achieve economic thresh level over T2 (60% fresh curd) and T1 (38% fresh curd) respectively. Lower curd size recorded with T1 (16 cm) followed by T2 (18 cm) and T4 (20 cm). T3 recorded highest weight of the curd (2.7 kg) as compared to T1 (1.25 kg), T2 (1.5 kg) and T4 (2.0 kg). Highest available form of boron in the soil is found in T3 (37.50 ppm) followed by T4 (35.0 ppm), T2 (30.62 ppm) and T1 (27.4 ppm) respectively. It is clearly understood that Treatment T3 <em>i.e.</em> FYM @ 10 t/ha + Boric acid (20% B) @ 0.3% as foliar spray after one month of planting emerged out to be the best treatment in respect to yield, curd size and weight of curd.</p> S.
