Coffea Arabica L

Arabica Coffee is an important export commodity for Ethiopia, contributing 25 to 30 % of the country’s total foreign exchange earnings. Moisture stress is one of the major constraints of coffee production in Hararge, Eastern Ethiopia. Moisture stress affects the growth, yield and quality of coffee. Local coffee landraces are source of desirable traits including moisture stress tolerance. Accordingly, this study was conducted to evaluate Hararge coffee landraces for moisture stress tolerance. Treatments consisted of 200 coffee landraces (178 from seven districts of east Hararge Zone and 22 from two districts of west Hararge Zone). The coffee landraces were field planted in July 2005 at Mechara Agricultural Research Center using augmented design with six trees per plot or accessions. Moisture stress tolerance was recorded from three randomly selected coffee trees per plot, three times a day (in the morning, noon and night) from January 05 to 25, 2014.  The stress tolerance was determined using 1-5 scale by visual scoring (1- all leaves green and turgid, 2- most leaves still turgid but younger leaves show leaf folding; 3- all leaves wilt or fold, 4- Leaves partially turning pales, and partly shed showing severe wilting and 5-leaves completely turning brown and dry, mostly dropping). The collected data were analyzed using descriptive statistics. The result of this study revealed that the coffee landraces varied in their level of tolerance to moisture stress. The 200 coffee landraces were grouped into seven clusters based on their level of tolerance to moisture stress. Nine coffee landraces (4.5%) were highly tolerant to moisture stress, 25 (12.5%) were tolerant, and 36 (18%) were moderately tolerant.  On the other hand, 60 coffee landraces (30%) were less tolerant; while 57 (28.5%), 11(5.5%) and 2 (1%) were moderately sensitive, sensitive and highly sensitive to moisture stress, in that order.  There was variation in coffee landraces for moisture stress tolerance both between and within areas of the collection. Hence, it is advisable to maintain and use promising coffee landraces in coffee breeding. Screening of the landraces under controlled conditions like green house and studying of mechanisms of moisture stress is also the way forward.

The Impact

A field experiment was established to study the impact of foliage fertilization of microelements (Fe and Mo) on lentil at the Agricultural Research Farm Mingora, Swat, Pakistan in 2016-17. All the treatments were assigned in random block design. The results showed that iron (Fe) and molybdenum (Mo) significantly improved the yield and quality of lentil crop. Based on the obtained results, the majority of the parameters increased with the combined application of Fe and Mo. The combined application of Fe and Mo at 500 and 100 g ha-1 produced the maximum grain yield (1361 kg ha-1), biological yield (3126 kg ha-1), 1000 grain weight (54.62 g), protein percent (30 %), N uptake (65.32 kg ha-1), Fe (48.33 mg/g) and Mo (5.07 mg/g) concentration. Results further revealed that Mo at the rate of 100 g ha-1 significantly enhanced the number of nodules (9.13 plant-1) and active nodules (8.03plant-1). These results suggested that Fe and Mo in optimal amount solely or as a blend considerably improve the growth, yield and quality of lentil crop and is therefore recommended for the better production of lentil crop in the agro-climatic condition of Swat valley.

Greater attention should be paid for increasing the yield per unit area by growing modern varieties of rice through improved cultivation practices. An experiment was conducted for investigating the effect of variety and date of harvesting on yield performance of modern rice varieties during Kharif, 2012 at Agricultural Research Station, Bapatla. The experiment was laid out in a split-plot design with three replications. Main treatments comprised of four rice varieties namely, BPT 5204, BPT 2270, BPT 2231, NLR 34449, NLR 28523 and MTU 1010 and sub treatments comprised of three time of harvesting viz., 25, 30 and 35 days after flowering. Plant growth, yield attributes, yield and quality of rice varieties were significantly influenced by different dates of harvesting. BPT 2270 was found significantly superior to all other varieties in respect of effective tillers, grains panicle-1, grain yield, straw yield and hulling per cent, milling per cent and head rice recovery. Among three harvesting times, the highest grain yield (6250 kg ha-1) and straw yield (7314 kg ha-1) were obtained when the crop was harvested at 30 days after flowering. The interaction effect of variety and date of harvesting was significant in respect of grain and straw yield. The highest grain yield (7771 kg ha-1) was observed in BPT 2270 when harvested at 30 days after flowering. Therefore, optimum date of harvesting for higher grain yield may be 30 days after flowering for avoiding immature stage as well as shattering loss.

Yield And Quality

Water pumping restrictions of high-quality irrigation water from underground aquifers is affecting vegetable production in Southwest Texas. There is a need to develop efficient deficit-irrigation strategies to minimize irrigation inputs and maintain crop profitability. Our objective was to determine how growth, yield, and quality of cantaloupe (Cucumis melo L. cv. `Caravelle') are affected by irrigation systems with varying input levels, including drip depth position and polyethylene mulch. Stand establishment systems used were containerized transplants and direct seeding. Field experiments were conducted on a Uvalde silty clay loam soil. Marketable yields increased in the order of pre-irrigation followed by: dry-land conditions, furrow/no-mulch, furrow/mulch, drip-surface (0 cm depth)/mulch, drip-subsurface (10-cm depth)/mulch, and drip-subsurface (30 cm depth)/mulch. Pooled across all drip depth treatments, plants on drip had higher water use efficiency than plants on furrow/no-mulch or furrow/mulch systems. Transplants with drip-surface produced 75% higher total and fruit size No. 9 yields than drip-subsurface (10- or 30-cm depth) during the first harvest, but total yields were unaffected by drip tape position. About similar trends were measured in a subsequent study except for a significant irrigation system (stand establishment interaction for yield. Total yields were highest for transplants on drip-subsurface (10-cm depth) and direct seeded plants on drip-subsurface (10 and 30 cm depth) with mulch.

In agricultural production, nitrogen loss leads to economic loss and is a high environmental risk affecting plant growth, yield, and quality. Use of the N fertilizer with a urease inhibitor is thus necessary to minimize N losses and increase the efficiency of N. This study aimed to evaluate the effects of N-(n-butyl) Thiophosphoric Triamide (NBPT) on the growth, yield, and quality of pineapple. The experiment involved two foliar fertilizer treatments: 1% (w/v) urea solution with NBPT (2.25 mL kg−1 urea) was treated as NLU (NBPT Liquid Urea), and the same concentration of urea without NBPT served as the control. Both were applied 12 times, starting 1 month after planting (MAP) and continuing once a month for 12 months. The application of urea with NBPT notably increased the above-ground dry biomass per plant (20% and 10% at 8 and 12 MAP, respectively), leaf area per plant (23% and 15% at 8 and 12 MAP, respectively), N accumulation per plant (10%), PFPN (Partial Factor Productivity) (13%), and average fruit weight (15%) compared to the treatment with urea alone (control). The analysis of quality parameters indicated that urea with NBPT improves TSS (Total Soluble Solids) (19%), ascorbic acid (10%), and sucrose (14%) but reduces the total organic acid content (21%) in pineapple. When using urea with a urease inhibitor (NBPT), there was a significant improvement in growth, yield, quality, and nitrogen use efficiency, with the additional benefit of reduced nitrogen losses, in combination with easy handling. Hence, urea with a urease inhibitor can be used as a viable alternative for increasing pineapple yield by boosting growth with better fruit quality.
